I wanted to be able to display images in my SLIME repl, so that I could do stuff like http://collison.ie/img/google-charts.png. I played around with swank.lisp and slime.el for an hour, and hacked together something that mostly works. The code is ugly as sin, but I'm posting it here in case anyone wants to similarly subvert their SLIME installation. If there's any interest in having this be a part of the SLIME distribution, I'm happy to look at cleaning it up...

I, too, hacked something like that not long ago: http://common-lisp.net/pipermail/slime-devel/2008-April/007264.html A few days later I mutilated it to be a slime contrib (but still requiring the SLIME-REPL-EMIT change), which follows (don't ask about the license :). Because it receives a filename to display, it is more low-level than your interface. It's easy then to write a simple CL function to fetch and display and image (say, using Drakma). (It's a git diff, I use the git://github.com/nablaone/slime mirror.)
