A lot of what you are doing has already been done by the folks at Project Gutenberg. Try
here for a listing of the books they have already converted. The zipped HTML files contain the images if available. I have used PG as the basis for many books I have posted.
Flogiston has already converted and posted several of Pyle's books to LRF format for the Sony. Robin is posted
here. Sadly, no PRC version for the Kindle.
