this may be a dumb question, but i can't seem to figure out how to keep my still images at their original size. it seems that no matter what i do, they always stretch to fill the screen. i've gone to the pan/crop window and set "stretch to fill frame" to 'no' - but no dice. i've tried everything i can think of, and even small images (say 100px X 100px) still fill the entire frame, and therefore look terrible. i can use the pan/crop to zoom out, but i'd like to know how to have my image stay at it's original size. in the pan/crop window, the width and height are listed correctly, but yet the image fills the screen.
