I'm no computer guru, but if you have a photo editing program that will allow you to save / convert those BMP files as Jpg, or possibly .gif
they will be MUCH smaller. BMP is the most bandwidth hungry file I know of.

After saving them as JPG, then zipping them may make them even smaller and most everyone has some form of winzip on their computer. (Dont know about the Mac and Linux guys?)

Thanks again for your hard work.
