Subject: modified this code to use the newer media handling routines.
X-Git-Tag: prexmlproducerconfig~315
X-Git-Url: http://erislabs.org.uk/gitweb/?a=commitdiff_plain;h=709fadec2f3860cb5fbc8d9d9528f132d7b6ad53;p=mir.git

modified this code to use the newer media handling routines.

images seem to work more or less fine.  may need some tweaking.  they show up on the edit menu at this point, at least.  hoorah.

theoretically, one could use this same Module "as-is" to add
non-image media to media folders and articles.  results will probably be unpredictable and potentially amusing.
