From bug 3877, the image for this fragment:

was rendered to: http://en.wikipedia.org/math/48287d2c5dacab82a7a4b46638ee6781.png
It should be automatically moved when used in a page to
http://en.wikipedia.org/math/4/8/2/48287d2c5dacab82a7a4b46638ee6781.png
however it doesn't seem to do so. Stick in a preview on the enwiki sandbox, and you get
the new URL but the file doesn't move.
