What did you use to try and crunch the images? I answered a similar question oh Webmasters. I've had fantastic results with PNGs. Photoshop is absolutely awful with saving, especially if you don't use Save For Web/Devices. http://webmasters.stackexchange.com/questions/13/what-can-i-do-to-reduce-the-file-size-of-my-images/441#441
