At the moment ebook files, other than PDFs, have a boring thumbnail based on their filetype. Whereas PDFs, PNGs etc. display the front cover, so at the moment the behaviour is not consistent
p.s. Sorry if this is on the incorrect thread, please move if it is.
You are in the correct place until the forum gets re-arranged.
Your screen slot indicated you are messing about under Calibre's skirts.
please read this sticky: https://www.mobileread.com/forums/sho...d.php?t=119175
You can view books internally with Calibre's Viewer.
When you used the Installer: Calibre should have set a file association to use 'E-Bookviewer.exe'
You can set your own choice (mine is set to use Sigil as the default)
BTW this work on Ubuntu version through Natty (11.04)
