Make sure the background/transparency color is the pure color and the same color as the original. The easiest way is to just fill over the background with the correct color. I had to fill over the background's for Rutabega's images to get them to work; for some reason they were a little off.

Oh, and why does the transparency go away in this image? I used the same color for the background as the rest (in fact, it's just a modified graphic from rudabega with blood in it)
