Try this one. I think that's what I am using. The trial version should be for free. At least mine was/is. I'm not sure whether it became time limited or not.
Additionally, I'm not 100% sure if it works with pictures. But I think I can remember me copying a film from the iPod back to the PC, therefore I guess it should work with pictures too:
Just try it out. It should be compatible with all, or most versions of iPod, including your iPod touch.
