Duplicate images should never be uploaded.
When a duplicate image is detected, we generate a detailed message identifying the duplicate. The message is always accurate.
We can easily detect when a pixel identical image is uploaded and we handle that automatically by rejecting the new upload and using the existing image instead.
If you make a minor change to an image so the images are not identical pixel by pixel, we compare the metadata for the images, including the date and time the image was created. If there is a match, we warn the user when they upload the image and ask them to resolve how the images should be handled. The matching process will not be perfect, which is why we ask authors to specify the action to be taken.
If you have a duplicate title, we warn the user, but add the Image Id to the title to make it unique. No action is required by the author.
Authors can merge together duplicate image using the menu "My Account", "Manage Duplicate Images".
Duplicate images for the organization or a specific member can be reviewed by Competition Managers using the same menu item.
