NEED TO SHRINK THE FILE SIZE? USE TRANSPARENCY

Want a killer tip for squeezing even more size out of your GIF Web images? Make something transparent. That's right, if you can pick an area of your image to make transparent, your file size will drop like a rock. For example, if you're putting a logo over a white background and you can make the white area around the logo transparent, your file size will be significantly smaller, because the transparent areas are virtually ignored when determining file size, because, after all, there's nothing there.
