HTC Droid Incredible

Can anyone tell me how to save pictures ive taken to the SD Card. I have taken many pictures and they are in the Gallery. All of them show up under 'All photos' under Albums. There are a few under Phone storage and one under 'SD Card', but how it got there I have no idea. When I try to download them to my computer I only see the 1 under SD Card, but have 133 under All photos. With my old phone, the 'Dare', I just chose menu and it gave an option to 'Move' and I could move them back an forth from the phone storage to the SD card just by selecting them. Please help?
