Use Advanced Search

Create a listing

Step 1

Click on the menu icon on the top right hand corner of the web page, then click ‘Create a listing’.

Step 2

Fill out all the relevant details and add images or a video. Simply drag and drop your images from your device onto the MAD On C box shown.

Step 3

Choose the category for your listing thoughtfully, it will only appear in the category you have chosen unless you duplicate the listing elsewhere.

Step 4

If you want to duplicate your listing in other categories, then:

1. Click 'Create and duplicate' once you have completed filling in your listing. This will create your original listing immediately and will take you to an exact copy of the listing form you've just filled out.

2. Because your previous listing's details have been kept, all you need to do now is to change the category to something relevant, but different from your initial listing category.

3. You can carry on duplicating your listing in all the additional categories you want.

Step 5

Once you’ve finished your listing (and the duplication listings), click ‘Create’.... and you are done.

Upload images

When you first sign-up with MAD On C, you will be prompted to add your contact details. This will include uploading an image to your profile using a drag and drop mechanism. Alternately, you can click on the image field and browse your computer’s files to select an image. Use the crop tool to frame your image and once you’re satisfied, click the tick button to confirm the upload. You can proceed to the next part of signing up by clicking ‘Next’, once all the other necessary details are filled out.

If you would like to change your images at any time, then you’ll need to edit your profile by carrying out the following steps:

  1. Go to your dashboard. This can be found by opening the menu in the top right corner of the website and selecting ‘Dashboard’.

  2. Clicking the 'Edit Profile' button in your dashboard will open a mini-window which allows you to change any imagery you may have already uploaded, as well as any other profile/organisation details you may wish to alter.

  3. If you wish to remove an image, simply click on it in the 'Edit Profile' mini-window and then click 'Remove'.

  4. If you would like to upload a new image or replace you've deleted, you can do this from within the Edit Profile section as well. To do this, drag and drop an image into the image area to upload it. You can also do this by clicking on the image area in order to browse your computer files for an appropriate image.

  5. Once the image has uploaded, use the crop tool to frame it. Once you are happy with the framing, confirm the picture by clicking the tick button.

  6. Once you have made the changes you need, you can save and close the mini-window and your profile will be updated.

Upload videos

How do I upload a video to MAD On C?

Video is a popular and growing means of communication and so it should be for Collectionibles. Less so for coins, stamps and other ephemera, and certainly so for larger items with more aspects or views to them. 

You can upload videos or images as you please to MAD On C.

 MAD On C uses YouTube to host our videos, so it’s important to note that YouTube accepts the following video formats: .MOV, .MPEG4, MP4, .AVI, .WMV, .MPEGPS, .FLV, 3GPP, WebM. If you don't know what your format is, don't worry its most likely to be one of these are they cover 80% of applications.

 If you know or find out your video is not in one of these formats, then you will need to convert it into one of them. Use this troubleshooter to get started.

Steps to Uploading a video


You are going to need a YouTube account. If you have a Google/YouTube account, then simply log-in. If you don’t have an account yet, you can register for free here.

Step 2. 

Once you have set up your account, you are now ready to upload your ideo to that account. Simply click on the 'Upload' arrow on the top right side of the YouTube page.

Step 3. 

Before you start uploading, select the privacy settings for your video. Please note that if you want others to be able to see your video on the MAD on C web site you need to select the 'Public'option shown.

Step 4. 

Now, back to the video. Select the video you want to upload. Simply click on it and drag and drop the video into the space shown and your video will begin to upload. This works for a video and a slideshow.

 Step 5. 

Once the video has uploaded click 'Publish'.

Step 6. 

Now to link your video to the MAD on C web site listing. Click on the YouTube menu bar at the top of the page on the left hand side. Click on My Channel. This will then take you to uploads . Simply click on the video you wish to upload to MAD on C. Now you have to click on the URL for the video (this is the web address of your video) and copy the URL. You need to copy this URL address onto your listing on the MADonC web site.

Step 7. 

Almost there ... now head to the listing you want to make on MAD on C. Now head to MADonC to create a listing. Paste the YouTube URL in the text field under the ‘Upload video’ section. Fill out any other details you need to on the page, then click Create.

PLEASE NOTE: If you want to disable advertising on your videos (recommended, as MADonC members may find the advertisements annoying), then please carry out the following steps:

To ensure all advertisements are completely removed from your videos, please remove all copyrighted material from your YouTube account.

Provide quality images


Good quality images are important to us at MAD On C, because they help others view your collectible as well and as fairly as possible. With this in mind, we’ve put together a guide to help you get the most out of your images.


Any flat collectibles, like stamps or postcards, can be scanned if you have a scanner.

To do this:

  1. Set your scanner to scan at 72 dpi.

  2. Once your image is scanned into your computer, open it in a photo editing program. This could be Windows Photos, iPhotos or others.

  3. Using your editing program, crop the image to be as square as possible, whilst keeping the object centred.

  4. The minimum dimensions of your image after cropping should be 700x700 pixels and the maximum dimensions 2048x2048 pixels.

  5. While editing, please do not add any filters to your image, as this may obscure important characteristics of your collectible from other members.

  6. When you’re done editing, save your image and check the file size. If it’s over 1MB, you may want to consider reducing the size of the file. 

  7. Once you are finished editing and resizing your photo, save it and upload it to MAD On C.

Taking a photograph (using a camera)

Any non-flat collectibles will need a photograph taken. It’s important your photographs are of good quality, so that other members get the most accurate impression of your collectible.

Please note:

Our galleries all have square image displays, so your uploaded images will be scaled to fit our image portal, which is a square box.

The minimum dimensions of your image after cropping should be 700x700 pixels and the maximum dimensions, 2048x2048 pixels, with a recommended dpi of 72 or more.

Here are some tips to help optimise your photographs:

  1. Background

Always try and have a clear or white background for your photograph. If the background needs to be a colour to show off the collectible, then make sure it’s a solid colour - preferably a light colour. If you’re struggling to find a good background, you can always put your collectible on a white sheet from around the house, or in a clean white bathtub.  Make sure there are no objects or people in the background to distract from your collectible. Never take the photograph whilst holding your collectible!

    2.    Lighting

Take your photos in a well lit area, so that your collectible is highly visible. Make sure that the majority of light is shining on the front of the collectible, not coming from behind it.

    3.    Focus

Make sure your photograph is well focused as you take it, but check it again for quality when you upload it to your computer. Look at your photo at 100% magnification to check for any blur!

    4.    Uploading images

Once you’ve taken your photographs, upload them to your computer as you ordinarily would. Once you’ve uploaded them to your computer, double-check them for quality before moving to editing.

    5.    Editing

You are free to use whichever editing program you like, so long as it has the crop function. Windows Photos and iPhoto are fine for cropping, although other programs will also work.

  1. Open your photo editing program.

  2. Crop the photograph so that the image is as square as possible, with the collectible centred.

  3. Please do not apply any filters to images you upload to MAD On C, as it may obscure important qualities of the collectible from other members.

  4. After you’ve finished editing, check your file size. If it is over 1MB, you may want to reduce the image. Reducing an image is different for Windows and Mac users:

Mac users

  1. If you’re a Mac user, open the image in Preview.
  2. If there is no toolbar showing, click the ‘Show Markup Toolbar’ button , then click the Adjust Size button
  3. Make sure image maintains its proportions, by selecting “Scale Proportionally”
  4. You can then reduce the image either by % or by manually adjusting the dimensions (These will be kept in proportion since you selected “Scale Proportionally”).
  5. Once you’ve finished resizing, make sure you save your image and you’re ready to upload to MAD On C!
  6. If you want to reduce multiple images at once, simply open the file the desired images occupy in Preview. This will open all those images in one Preview window. Select them all and carry out the same steps as you would for reducing a single image.

Windows users

  1. If you’re a Windows 10 user, there is no built-in photo reduction program, so you’ll need to download one if you have not already. We recommend downloading FastStone Photo Resizer for free here.
  2. Once you’ve downloaded and opened the program, you can drag and drop the images you want to reduce from your program files to the Input List on the right of the program interface.
  3. Once your image(s) is on the Input List, tick the ‘Use Advanced Options...Resize’, then click the ‘Advanced Options’ button which appears.
  4. In the Advanced Options, click on the Resize tab and select the box. This will bring up your resizing options.
  5. Select that you want to resize it by %, and choose what % you would like the image reduced by.
  6. You can view a preview of the resizing by clicking the Conversion Preview button
  7. Ensure that no filters are selected before pressing ‘Ok’ to close this window, which will return you to the main interface.
  8. Click ‘Convert’ and the program will resize your image as you’ve set it to. You will be prompted to save the newly resized image(s) in a folder - use a different folder to where the images were initially stored.
  9. Your images have now been successfully resized!
  • Once you are finished editing, save your photo and go here for help uploading it to the MAD On C website.

Photographs from Mobile Phones

In many ways, you can treat mobile phones as cameras. Therefore, to take a good photograph with a mobile phone, follow the step by step guide above, for how to take a good photograph with a camera.

Some notes on Mobile Image sizes:

The size of your photograph will be determined by the camera quality settings you have on your phone. If your image is over 1MB we would recommend reducing the file size before uploading to MAD On C. You can either send the image straight to your computer (via email, dropbox etc.), and reduce it using our instructions (link/bookmark to image reduction instructions)  or you can reduce the image size on your phone if you have an app with that functionality. If you’d like to do this, we recommend downloading Photo & Picture Resizer from the Play Store if you’re on an Android device, or Shrink My Pictures from the App Store if you have an iPhone.  Follow the instructions on the respective apps to shrink your image file sizes. Once that’s done, you can save your images and upload them to MAD On C!

If you’re uploading images straight from your phone to MAD On C or emailing them to yourself to edit on your computer, make sure you do it over a Wi-fi connection, otherwise, it can consume lots of your mobile data.

Search for objects

There are two search engines on MAD on C, the General Search Engine at the top of the page and the Advanced Search Engine on the left of the page. 

 The General Search bar

 The General Search bar is best used for searching categories and items rather than events and directory listingsIt's simple to use. Type in the category heading of what you are looking for or just a simple word, and categories related to your request will appear in the drop-down menu. Select a category which seems appropriate or simply search whichever search term you’ve entered. 

The Advanced Search Bar

The advanced search has a series of filters that enable you to be specific in different ways about what you are looking for. For example, geography or location, which makes it much more suitable for searching events and directories.

A unique feature we have included is the ability to search different galleries and marketplaces. Clicking on the marketplaces creates a drop down menu of different marketplaces for different purposes, for example, 'events', 'directories', 'sales listings' and much more Then you can search these with all sorts of further filers shown below.

 Automatic 'Saved Searches' 

Towards the bottom of the advanced search options, you will see that you can 'Save Searches'. Simply provide a name for the search you want to save and you will be given the option of being notified of new listings relevant to your search 'never', 'daily', 'weekly' and 'monthly'. It will do it for you automatically! So daily, weekly or monthly you will receive emails up dating you on new listings. 

 If you want, you can then click on saved searches, and the 'Default' option means that when you next log in to MAD on C, it will automatically show the results for this saved search.

 You can also see your email notifications in your account dashboard.
