I noticed something with that last comic before this one.
If you're using Paint:
When you've pasted a sprite into the comic, on the side beneath the tool bar, you can select between transparent or solid, the back color on the color bar is what will turn transparent once you select that.
On Photoshop, Paint.Net and the others, you can easily erase the background before the sprite becomes one with the panels.
