Cool In was able to shave a few hundred bytes off my top image since it is now broken up in 3 images with only the top left containing the actual image. The rest are alot smaller than the ones you have packaged up with most being 41 bytes. However I can't get past the Photo Quality Images I use in that NOW top left image. The smallest one I have done is 1450bytes which beats the 1750bytes before.
I went one step further knowing graphics a bit and converted the gif down to a jpg which shaved it down to 1125bytes.
Most of the graphics you have packaged up can be compressed to one half or even a quarter of their size with any good graphics compression program. This will help save bandwidth and load time as well. This is what I had to do as we would not even want to try to load the images I created without compressing them.
