#: Image file types to treat as ebooks when dropping onto the Book Details panel
# Normally, if you drop any image file in a format known to calibre onto the
# Book Details panel, it will be used to set the cover. If you want to store
# some image types as ebooks instead, you can set this tweak.
# Examples:
# cover_drop_exclude = {'tiff', 'webp'}
