Does anyone have any ideas on how to turn a digital picture frame into an e-book reader?

I've been looking around  for an affordable e-book reader but they all seem to be north of $200. While at the store the other day I passed some digital picture frames that were under $100 that were the right size and shape. The digital picture frame looks like it has all the hardware you'd need: lcd screen, media port, etc, problem is getting them to read pdf files and the like. I thought about finding a way to convert pdf files to jpeg files but that seems like a hassle to do every time I want to read something. Has anyone out there attempted to hack one of those digital frames so that it reads more than just image files?

you can use http://www.tracker-software.com/product/pdf-xchange-viewer, which is free and can convert pdf to jpg. something more complex: https://www.instructables.com/id/How-to-convert-e-text-book-to-images-and-read-it/

has some stuff on a firmware hack for specific frames to make them run live video. I've tried a bit with a few others, but my embedded-firmware-fu isn't up to par. They're usually rather puny processor wise and hardware docs/specs are rarely to be seen so it's a pretty large project to try to reverse engineer one and they usually have lots of small and big differences so most firmware would be good for what is in front of you only.

PDF to JPEG is probably your best bet, alas, unless you can figure out how to replace the processor with one that has a PDF renderer in its firmware.

Well, I'm not a techie, but I'm gonna wild a** guess that you can't do it. Not in any practicable sense anyway.
