cdcover is a shell script that acts as a nice wrapper around Ben Fitz' cdlabelgen. It handles JPG and GIFs, scaling, postscript conversion and a few other details relating to cdlabelgen options.
Naturally, this has the status of "neat hack", and is closely-coupled to Amazon's HTML formatting du jour (last updated: 29 Mar 2003). But it works, and it saves time. Feel free to use it to make nice inlay cards for your, er, legitimate backups. :-)
It requires Linux, and uses a bunch of shell tools (sh, perl, tee, etc) and many more Linux-specific hacks (lynx, xview, gv, djpeg, PNM tools). You will need to install cdlabelgen too.
