Hi Jonathan
Many thanks for the information. I had never considered .png before, simply because .jpg has such good resizing qualities without much loss in quality, although as you say it was a little fuzzy on line drawings. Great news re Calibre though.
Correct me if I'm wrong, but I don't think that mobi is a good medium to showcase reference books. For one thing it is not very easy to refer back to something. I also have problems with the formatting from epub. Line spacings and text orientation get messed up sometimes.
Here's the process I go through, I would appreciate it if some kind soul could let me know where I can improve on it.
I write or edit in a word processor, I then copy it into Sigil and clean up any formatting there and save it as an epub. I then take it into Calibre and convert it to mobi. This is where the problems start. I realise that the Calibre reader isn't perfect, so I open the mobi on my desktop Kindle. Not too many problems here, but when I load it onto my Kindle 3G, the text is all over the place.
Maybe Kindle isn't ready yet for illustrated books, but I believe it is the market leader for ereaders, so obviously I'd like to exploit that fact. It was so much easier in PDF, but then that wasn't mobil.
