问题
I can't find a solution to this. I want to add 20px empty space to this image: http://img233.imageshack.us/img233/419/78317401.jpg
and then paste this watermark at the bottom (on the blank space)
So the output would be:
http://img252.imageshack.us/img252/4554/wynik.jpg
I don't want to stretch it.
EDIT
Did it with WIdeImage. Rly simple.
