Other nice capability from ImageMagick. 

In ~/.mailcap, I have,

# From Laurel on Linuxchix for lynx and pictures
image/jpeg; display '%s'; test=test -n "$DISPLAY"
image/gif;  display '%s'; test=test -n "$DISPLAY"
image/png;  display '%s'; test=test -n "$DISPLAY"

Run Lynx in X, follow a link to a file that's a picture, and
instead of "it's a picture, download or cancel?" prompt get
an ImageMagick window with the pic in it.

I actually find myself typing "display somefile.jpg" instead
of starting gimp or pho or xv or gqview or whatever these days: 
way faster!

Hadn't met that one. Handy.
