My animated gifs are too large!

How bring down my animated gif file size?

Keep in mind that an animated gif is really several images with a 
display script.  You need to design the images so that only the 
information which changes is stored and this will keep your file sizes 
at a minimum.
Lower your color depth.  Remove all colors which aren't an essential 
part of the image.
If the image order is a, b, c, d and the entire left side of the image 
never changes then have the entire image in a only, and the right side 
in b, c and d.
Try to reuse frames.  If the frame order is a, b, c, d and d looks 
just 
like a then create the animated giff to go a, b, c, a thus reusing 
image a instead of putting an identical image in the gif.
Also look at initial size of the image bunch
