Timed in-game screenshots

Does anyone know of a good free/trial program that I can use to take timed screenshots in-game for PC? I used SnagIt, but my 30 days ran out for that.

Requirements:

• Must be able to set a timer to how often pictures are automatically taken.
• ...must be able to automatically store these pictures somewhere!
• Must take screenshots at full resolution.
• Must (obviously) be able to take screenshots of a game.

Pirate fraps.

Why would you want to set a timer?

If you have some foot pedals from a steering setup, grab the free version of Fraps (which snaps in full res and saves in BMP...which is what you want anyway) and bind the screenshot hotkey to the gas/brake. Does wonders.

In absence of a steering wheel setup (I nabbed a cheap one on clearance for $15), you could always use a second keyboard with the spacebar bound to screen cap. Tap it with your toe for picture lovin'.
