Syncing photos doesn't appear to do anything I have a ton of photos on my iPhone (4S, although most were taken with my previous 3G). I am trying to sync them to my computer (Windows Vista) but they are not appearing there.

I went to my iPhone in iTunes, clicked the "Photos" tab at the top and selected a folder. After synching, that folder now has a subfolder "iPod Photo Cache" with one file "Photo Database" that is 892 bytes.

Where are the photos? Do I need to do something different to actually copy the photos to this folder?
The "photos" tab in iTunes is for syncing photos on your computer to your iPhone. To download the photos off your iPhone, use some software that downloads photos off cameras, such as Windows Photo Gallery.
