Speaks for itself. If you only have one piece of media for whatever
reason, the navigation still shows up. But both of the buttons are
disabled, so they may just as well be gone completely.

I have no idea how hard this is to do though.

Attached is a screenshot.

Right now we have next/previous buttons like: []

The problem: it's confusing. I made a suggestion on how to fix this
once, by reversing the order of the arrows:
`http://bugs.foocorp.net/issues/423 <http://bugs.foocorp.net/issues/423>`_

However I'm not sure this really makes things clearer. Either
ordering is confusing here:


-  [] is what we used to do but this is confusing because our
   galleries go in the opposite direction (newer on left, older on
   right), which is what makes sense for a gallery to be like.
-  [] is what we do now, but that's also totally confusing. Who
   really expects arrows to point this way? Not me (even despite
   filing that old ticket). Imagine reading a webcomic ordered this
   way. That would be crazy! So here's some suggested resolutions:
-  Switch back to the old behavior and add text to the arrows, like
   []
-  Add smaller-thumbnail support (75-100px?) and make these
   thumbnails the navigation.

I'd opt for `#1 </issues/1>`_... maybe we can make #2 a different
ticket and add an ajaxy "quick browser" like flickr has that's
scrollable left and right, and make that **separate** from the
current next/previous arrow buttons. Bonus point: doing
`#1 </issues/1>`_ will fill up some of that glaring whitespace on
those current buttons ;)

Dropping this in Jef's lap! Jef, what do you think?

We could really use a mediagoblin favicon! Not all instances have
to use it, but it'd be nice to have in.
