It gets weirder. I found a free utility called PNGenie that successfully reduced the collective size of my 206 PNG images from 19MB to 10MB. My EPUB is half the size it was before, yet when I convert the new EPUB to a MOBI in Calibre, IT IS STILL 40MB. That's Just Wrong. Cutting 10 MB from the images should have cut at least 10 MB from the MOBI file size. something is definitely wrong here.
