How come in Windows photo gallery it doesnt detect if a picture already exists when you want to import new pictures? You end up with multiple copies of the same pictures because when you get ready to import them it doesnt let you pick what pictures you want to import. It just imports everything that's on your memory card over & over again. Picasa has a watched folder option so it knows when you get ready to import new pictures which 1's already exist & what's new. Photo gallery acts like it's new pictures all the time.
