When I go to http://www.creativepro.com/story/feature/17898.html they talk about making a drop shadow in a Gif. I can't figure out how to do it the way they talk about. Whenever I try to do a drop shadow to make it look like the one they did it just comes out with a plain solid black background. Could anybody look at what they did and tell me how to do it so I can get the shadow effect? Thanks in advance.
