On the image comment, I noticed this as well. Just about a month back, I added the KSM07 Menu, and started using CoolReader(which I liked to use with the Nook STR),
and looking at the same books with images i noticed that coolreader renders them larger..
May be something to try..

It works fine on the Kobo Aura H2O.
