easier program to use than fraps: http://www.irfanview.com/
all you have to do is open up the screenshot which you took, which is in the TGAS folder, then "save as" then you can choose which format to save it as, preferably .jpg, which is what i do.

you can even then later open upo the picture in "paint" or some other program, and add stuff like blood to make the pscreenshot cooler than it really is.... lol!
heres an example, along with a comment by the person subject to the slash:
