This can extract thumbnails from epub and fb2 ("fiction book", both zipped and unzipped) files.
Works great for most of my ePubs. Here's an archive of some public-domain books in my collection that don't work.
How about "eBooks" or "eBook Files" (a more common term, and all the other entries are plural)
Quite lovely. With the latest changes, this now generates thumbnails for all my my ePubs that have a cover page defined.
VDG,approved, still needs a proper code review.
PLUGIN_INSTALL_DIR is deprecated, new code should use KDE_INSTALL_PLUGINDIR
do we have a shipit? Looks good to me too!
