My question is, "Isn't it a good idea for mods to place images in sets while they're approving?"
I think this will save mods down the road some time as they can add to the existing sets and this will also help with limiting duplicate images.
Also, it makes it easier for members to check for existing images and then to upload missing images.
Here is 1 example....
Wizard of Oz (1939)
I added 36 images to this title and it took me a while to make sure I wasn't adding any duplicate images. When I uploaded, I tried to keep them in sets to make it easier for the mods to check for duplication.
