Fix for the page jumping on thumbnails
Test for the fix for the annoying jump-to-top-of-page that happens when clicking on a thumbnail image. This is based on this Google post.
This should also allow the full images to be viewed by browsers not using Javascript. Now to go back and change the old posts (basically, changing the href, adding a blank target, and putting a “return false” at the end of the onClick action, so the href doesn’t trigger; probably easiest to do this by hand, since there only about a half dozen such links).
