Why didn't I get the transparent GIF image?

Sometime, you may have a perfect transparent image in the Photobie editor, but when you save it as a transparent GIF file, there is a background in certain color, which makes it not transparent. It happens due to the Photobie tries to set the GIF transparent color as the Global transparent color, it works if there is no dominate color in your image that is close to the Global transparent color. So, the solution is simple, set the Global transparent color to whatever color that isn't in the current image before you save it.

Bingo!
