Now I dont see where there is an issue with editproduct at all here. Here is how the ad upload process works
1. You upload an ad ( we check on initial upload for an ad posted by you with the same filename. This is to prevent someone posted there ad twice. Sanity check for those impatient posters much like a forum double post check
2. You can edit a product and ad other images. Now if you want to add the same picture again 2 more times go for it. Thats your choice. I dont see a problem here.
