Taking Photos on PS3

Anyone know a better way to take photos while in game on the PS3 without using a camera? Any software/hardware that will take in-game shots; for dynasties or interesting/funny photos or bugs/glitches and stuff? What do you guys use?

Some games let you take screenshots by pressing PrintScrn on an attached USB keyboard. Otherwise, if your PC has an S-Video input, just connect it to your PS3 and you're good to go (I assume there's a certain type of application involved, though I don't know its name.)

Really!? And would it save the screen automatically on the HDD? We can't paste and save it like in Windows, can we.
