zgv (svgalib picture viewer) zgv is a picture viewer with a thumbnail-based file selector. It supports most popular formats and allows panning and fit-to-screen methods of viewing, slideshows, scaling, gamma adjustment, etc. By default, the zgv binary is installed suid root, but we have patched the build to not do this. Instead, we install a udev rules file that should allow non-root users who belong to the "video" group to use zgv. Note that you will have to "modprobe svgalib_helper" prior to using zgv. For more information, see zgvs manpage, info files and /usr/doc/zgv-*/SECURITY.
