So I've used Calibre 0.7.14 to put some EPUB-format books onto my stock Nook, and I noticed that along with the EPUB files it also uploads JPG files that just contain vertical lines in various colors. It looks like these are maybe supposed to be thumbnails of the book covers, but I guess something is going wrong with Calibre when it makes them. Anyone know what's up?

Thanks.

Edit: I've attached one of the JPG files so you can see what I'm talking about.
