Here's the thing, though: two people can't propose the same image to be added, because the system will see that as a duplicate.
However, if a person uploads a photo into the forums, then later goes and uploads the same photo directly into the database, the system does not know that this was the same exact photo. (It can't actually see the photo and know what it looks like. It can only look at the filename).
That's the only scenario where a duplicate could be created.
The real ultimate solution for this problem is to have the system programmed to be able to actually view an image and compare it to all other images in the database, and look for duplicates that way. This will be a huge challenge... it's going on my "really want to do one day" list.
