Program to capture sequential screenshots automatically

[Windrunner]

Hola!

I'm looking for a program to capture screenshots of a specific window sequentially, automatically, and quickly with the press of a hotkey combination. I want it to output files automatically.

While I'm in a window, I hit the hotkey, and in a directory, Screenshot01.jpg is created. I hit it again, screenshot02.jpg is created and so on and so forth. Is there FOSS/junkware free software that any of you know of that will do this?
