Description:
At the Commons, we have a lot of images that match the regular
expression

^[[:digit:]]+px-

See, for example,

http://commons.wikimedia.org/wiki/Category:Images_for_cleanup

Virtually without exception, these are MediaWiki's thumbnails that
users have accidentally downloaded from some other Wikimedia site,
and uploaded at the Commons. When uploading an file whose title
matches the above expression, we'd like a warning similar to
the "file with this name exists already" warning, that would say
something like

This appears to be a thumbnail that you just downloaded from 
another Wikimedia site.  Please go back and get the
full-resolution version to upload here.

With the same "Save file" and "Re-upload" options.
