The easiest way IMO is to connect to the PC in disk drive, "view files and folders" (if Windows). There's 2 separate instances that will come up b/c you should see both the internal memory and the SD card. If you open the one for the SD, close it and there should be another one for the internal. Other option is to use windows explorer or My Computer and look at them there...they'll be labled as a drive (perhaps F,G etc depending on how many other drives you have connected).
Anyway, internel pics are located at: /emmc/DCIM/100MEDIA
Copy/paste them to your SD card or PC for that matter. Might just want to use the settings in the camera to save all pics to SD as already mentioned. Up to you.
