I'm making one of those sneaky drop down menu banner ads. The hosting site banner ad specifications are to make a 133 by 100 pixel gif or animated gif within 12k. I have downloaded their page and have worked my code into theirs to make sure everything I do coordinates well with their design. It comes in at 12k and within size but it isn't just a gif of course, hehe. I hope they won't mind a little extra code.
