also curious about this. i know that apple's guidelines suggest that there not be more than 10Mb of images per chapter, but i doubt very much that that's any one else's standard.
if you have photoshop, you can save (non-transparent) images as optimized for web, and then adjust their quality to shrink them further.
you can do pretty much the same using automator with preview (if you have a mac), but the resulting images can be pretty bad quality.
i'm sure there are also other image editors that allow you to batch process...
