I upgraded my Kobo Glo from 2.1.5 to 2.5.1. As soon as covers started to be generated to the mSD card they all turned to garbage low resolution, no 3x4 standard on the size and white bars on the side. In spite of the fact that the parsed image files were two or three time the size of the old images under 2.1.5 the resolution was horrible.
I thought that I would have to revert to 2.1.5 for the third time!!!
I then noticed that my 5000+ images (all 3x4 std.) were still sitting in the images folder on the Main Kobo drive. I copied them all to the Images folder on the mSD disk and voila, everything works great. The images now have no side bars and the resolution is great on sleep, library and home screens.
I am now very happy with 2.5.1. I can use calibre to load all future images until Kobo figures out how to generate them as per firmware 2.1.5.
The above also shows that it is the Kobo firmware that is generating different images from the same Books and not that there is a problem with the books cover pages.
