TGrab - TGrab is a new type of "image
grabber": it can not only take screen-
shots in a manual mode, but also in a 
timer automated mode. You can take a 
picture at a preferred timer interval, 
during a time limited session and/or 
until a quantity of images is reached. 
If preferred, it can even run totally 
invisible and/or terminate itself when 
done. $25
