Moving pictures from Iphone photo folder to computer

The photo sync is one way: Computer to phone. If you synced these photos to your phone, you can only delete them from your phone through the iTunes sync process by deselecting them in iTunes, performing a sync, they will then be removed from your phone.

Photos transferred from your computer to your iPhone should remain on your computer and be included with your computers backup along with all other important data.
The transfer of photos from your computer is a one way transfer process only. Photos transferred from your computer are optimized for viewing on your iPhone as part of the iTunes sync/transfer process - the original resolution of these photos are reduced on your iPhone which is why transferring these photos in the opposite direction is not supported. If supported, the original resolution of these photos would be lost in the process, which is just one reason why all photos on your computer should be included with your computers backup.
