Sanyo MM-5600

Okay, how the hell to I move stuff back and forth from PC to phone. I did manage to move a pic to the card but when I tried to open it in the phone it was just a red dot with a white 'X' in it. The pic was a small JPEG. And how do I then move THAT to where I can assign it as a screensaver. Also, is it just me or does the users manual tell us dick? Where can we get more detailed info or tech support? I cant figure out half the **** on this phone.

Thanx.
