This doesn't work as I intended: the expression will always be true,
it checks for access rather than file existence.

It could be rewritten like

<!--#set var="IMAGE_BASE" value="/philosophy/category" -->
<!--#set var="IMAGE_EXT" value=".png" -->
<!--#set var="IMAGE_LINK"
 value="<img src=\"${IMAGE_BASE}${LANGUAGE_SUFFIX}${IMAGE_EXT}\" />" -->
<!--#echo encoding="none" var="IMAGE_LINK" -->

provided that .symlinks redirect all non-existing localizations
to the English image; when a new image is added, a link should be
removed. in theory, it can be done with a cron job running, say,
every five minutes.
