I totally understand the compatibility thing. Do you have any recommendations for decreasing the file size of the Calibre image conversions? I've got 10k gifs but even when I save them as jpeg with 0 quality settings they are coming up at 30k+.
It's brutal because I'm looking at having to pay a $2.25 "delivery fee" for the 15MB MOBI of a $4.99 book.
