Syncing the iPhone's photos to my computer?

So I take photos with my iPhone and sync them to the “Pictures” folder (Windows Vista… sigh…) because the system recognizes iPhone as a camera and asked me if i wanted to automatically sync it there. Now I’m tired of the pictures being in a different folder for each date (making like a million folders), so I made a folder called “Imported iPhone Pictures” which I intend to put the photos in. However, I don’t know how to go back and tell the computer “I don’t want to sync the photos to “Pictues” anymore, I want to sync them to “Imported iPhone Pictures”.

Every time I hook up my iPhone to my computer, Vista automatically syncs the photos to “Pictures”. There’s no way to change the folder I sync it to, or even quit syncing the photos every time. Can somebody please help?
