Make next / previous universally non-confusing (possibly with thumbs?)
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:
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?
