Plus it would take a long time to prepare each book.

800x600 seems to be a pretty easy-to-get (and cheap) resolution for the 8" frames (judging by newegg, at least)
I did a couple of minutes of playing with the one linked above by alyknight, and it let me specify height/width of the output images, font face/size/color, background color/image, and even jpeg quality if converting to jpegs.
Setting it to 800x600 image size, and a jpeg quality of 40% (it looks ok at that level on the computer screen; I don't have a photo frame to try it with) and converting a novel, I got 186 jpeg files, with the file size ranging from ~100-130kB each, for a total directory size of 21.8 megabytes.
It took my machine (Intel E8400 cpu) about 40 seconds to do the conversion. This converter, at least, is not multi-threaded, so multi-core isn't really a benefit.
If I switched it to PNG, the time to convert was approximately the same, though the file sizes shrunk and were in the 80-110 KB range.
If I added PNG Compression, they are absolutely right, it is a ton slower; I aborted the process two or three minutes in, and it wasn't halfway yet. File sizes were in the 40-70 KB range.
Your points about bookmarks/page you were on/etc are absolutely valid. It also might look a little weird at a coffee place or an airport to pull out a digital photo frame. Here in the US, I think that's grounds for a *very* thorough full body search by a guy named Bubba, and after that you'd get a complementary tazing.
