That model uses a DVDR/RW type discs plus a memory card (SD, MMC or Sony Memory Sticks). To view photos from the disc simply go into view mode and use the joystick to move to the image you want to view. If you want to transfer images you need the USB cable that came with it and the original software to transfer images from the disc. While capturing video you can snap images but only to a memory card/stick. No card/stick while shooting video, then nothing was captured and the only way you can get any images is transferring a frame(s) from the video using the USB cable and their included software.
Here are links to the manufacturer website where you can still download the software that came with that model and a second link to view/save the manual in PDF format. Information to read in the manual are on pages 95 & 108.
