Some images are being served full-size, not thumbnailed

Description

Gentlemen, on pages like
http://commons.wikimedia.org/wiki/Category:PD_US_Military
there is a big problem.

If any file's name starts with a digit, no thumbnail is produced.
Instead the whole giant image is pulled into the user's browser.

This is a big waste of bytes.

The software (please reassign bug if necessary) somehow thinks that
the image must already bear a NNpx number-pixel name, and must already
be a thumbnail, but this is not the case.

Of course this waste is hidden through many, many, many layers of CSS. And
there is also HTML "height=" and "width=".

But if the user is using a text browser like emacs-w3m, the giant
images "blow up in his face" to the true reality of the situation:
monster images amongst normal thumbnails.

The images that sail through without being thumbnailed with the above
example page are:
$ GET http://commons.wikimedia.org/wiki/Category:PD_US_Military |
perl -wlne 'm@src="http://upload.wikimedia.org/wikipedia/commons/./../(\d[^"]+)@&&print $1'
