My guess would be that the "1" is nothing more than some status return
value, saying "OK" (or "error", depending on which way round the logic
is defined). The image is probably modified in place, i.e. I'd expect
$bottom_img to hold the new image after the function was called...
Have you already looked at $bottom_img?
