Thanks for the reply! I was looking at this some more - I'm apparently
not the only one who has bumped into this issue:
https://mastodon.technology/web/statuses/104026801137372645

It looks like someone else was seeing lynx launch cura and Shutter at
different times. I ran lynx via strace to see if I could figure out what
was happening with the filename and discovered that it was using Eye of
Gnome:

write(1, "\33[93m\33[44meog /tmp/lynxXXXX9odQF"..., 52) = 52

At first that made sense to me, since I didn't have xloadimage
installed. But when I *did* install xloadimage, lynx still tried to
launch eog. After uninstalling eog lynx sent the image to Firefox (which
*did* happily ignore the extension). I also discovered that I could
launch the temp file directly with xloadimage and feh and both of those
happily ignored the filename as well.

So it seems that lynx is just picking the wrong viewer on my system. Is
there a way to configure what viewer lynx uses? I found
https://lynx.invisible-island.net/lynx2.8.3/breakout/lynx.cfg and
created ~/lynx.cfg and stuck this in it:

XLOADIMAGE_COMMAND:feh %s
VIEWER:image/gif:feh %s

Then I launched lynx with `lynx -cfg /home/wayne/lynx.cfg`, but it
didn't appear to do anything.

Thoughts?
