[Mediawiki-l] Help with External Images Display

[Rowe, Dolores A]

Teammates,

We would like to use the capability of $wgAllowExternalImages from
http://www.mediawiki.org/wiki/Manual:Linked_images#External_image_syntax

however, some of the images we would like to display do not have an extension in
the filename, even though they are *.jpg.  So for example, the *.jpg might simply
be named "StacyPic".

Can you think of any clever way to get around this issue ?  We are using MW 1.15.3.

Thank you,
L
