I used a file manager program to locate the pics on my internal storage and selected the folder. Then moved it over to my sd card photo folder. I used Astro File manager. It is free on the Market.
Well if you have access to a PC, just plug in the usb and select disk drive. On the PC look for the disk drives. Aside from your installed drives you should see two other drives, those are the phone storage and sd card. Find the pics on the internal storage drive and just copy and past to the SD card (drive)
