Hi - I have got a similar problem. Every time I install a new version of Calibre 4, i lose all cover art and the program won't let me add in new .jpg files as covers (says "ValueError: Failed to export image as JPEG with error:Unsupported image format"). The qtjpeg.dll file seems to be in the apps folder, but the program won't see any .jpg files in my library even though all are visible in v 3.48. I would like to upgrade to 4.18 now as also now having the problem with my paperwhite were cover art is being wiped whenever i connect online.

Anything you can suggest to help??
