I've been considering a rewrite of Apache::AutoIndex (if Philippe 
doesn't beat me to it), and maybe the thumbnail generation needs to be 
abstracted out into a separate module?

One thing that I had planned was to handle thumbnails according to this 
(proposed) standard:

  http://jens.triq.net/thumbnail-spec/

Which eliminates the clutter of thumbnail files (and the associated 
edge-case of "do not generate thumbnails for thumbnails") (and maybe 
also allows multiple web-based services to utilize a common thumbnail 
cache (I'll propose that ~/.thumbnails/ corresponds to 
$DOCUMENT_ROOT/.thumbnails/, but maybe there's a good argument for it 
living in $TMP (except that there the cache could get lost at reboot.))

That seems to be the consensus.  However, if you aren't doing anything 
very complex (e.g. just resize/rotate) it might be worth it.

ImageMagick does support more formats.

Maybe that would be better with IPC::Run?  (But I won't claim to know 
how the forking that it does interacts with a2/mp2 (yet.))
