The site I mentioned, Gnome Art is this: http://art.gnome.org/backgrounds It is where some people come to get nice background images, and not just Gnome users. For example, in my Windows PC at work I have a background from this site. So it would be good if pictures from this site could be displayed with grub2. They are just normal pictures. In fact I think the site could be used as a test resource for the grub2 background image feature, as it has images created by various people in various sizes and with various cameras and software packages. >> There is a file grub-core/video/readers/jpeg.c.

By loading the image files manually on the command line I got this error message for both problem files: "jpeg: invalid 0xFF in data stream" This comes from jpeg.c, line 124. I have created a bug report as you requested, unfortunately I could not attach the said files as they exceed the site limit. If you want I can email the files to you or upload to some temporary place of your choice. (The file sizes are 2.1 Mb and 577 Kb). _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
