showpicture - View an image received in the mail
[-viewer program-name] file-name(s)
program will allow a user on a properly-equipped
workstation to view a picture using the xloadimage(1) program. It is intended
to be called from mailcap files, typically by the metamail(1) program.
By default, the program used to display pictures under X11 is "xloadimage
-view -quiet -geometry +1+1". This can be overridden either by the
environment variable X_VIEWER or by the -viewer command line option.
Doesn't do much if you're not running X11.
