Cdesja5 and PeterT - many thanks for the responses. I must say, this is a revelation to me - I had assumed all the necessary information would be embedded with epub files. Which metadata files should I be looking out?
Oh, and any ideas as to why the Kobo fails frequently fails to display cover images within side loaded book, even though it displays on the shelf? I can't help but suspect there is some size issue here...
