Does The GIMP have some sort of function to highlight areas of the background where that are not overlapped by any layers?
I'm making a sprite for CSS, and I have a lot of pics with different sizes. I'm trying to use any free space that I can get, but because over 90% of these images have transparent background, so I can not see the borders of layers. I can't see where and how much background space is free for other small pics.
