The JavaScript URLs work fine, and they weren't too difficult to adapt to my
own MediaWiki installation. The URL rewrite stuff that redirects the 404 URL
to thumb.php is what seems to be missing, and it affects all image types. I
don't know what command is being used to render SVG thumbs. How do I find
that info? Here's the other info you requested, along with a copy and paste
of the section in my LocalSettings.php that deals with images:

Ahh, I see that was in the original mail. I didn't realize what it was at
first.

sumanah from #mediawiki suggested that I post
here. I set up SVG support
on
my wiki, and I got the javascript links to rendered PNG images working
to.
But, I noticed a few problems:
* SVG images distorted when thumbnails are generated using normal wiki
image
link syntax.
I have no idea why the SVG images are being rendered all weird.
ImageMagick's /usr/bin/convert seems to be configured correctly in
localsettings.php, and I don't see any problems.
What command are you using to make SVG thumbs? What distro, convert
package version, and convert version do you have? Are you using
imagemagick's convert or rsvg or something else?
I'm not sure exactly what rsvg version the WMF cluster is using but
you may want to try something from
http://packages.debian.org/librsvg2-bin
You say "seems to be configured correctly"... what exactly are your
settings so we can compare?
You can see @
http://noc.wikimedia.org/conf/highlight.php?file=CommonSettings.php
that the WMF cluster is using
$path/rsvg-convert -w $width -h $height -o
$output < $input
* I also discovered that when I clicked on the
link javascript links to
rendered PNG images, 404 errors were returned. This happens for ALL kinds
of
images when scaling is requested via URL.
In troubleshooting this I got as far as finding some info about thumb.php
and htaccess rewrite rules that are supposed to redirect the 404 URLs to
thumb.php so the images can be generated. It's all greek to me, and I'm
surprised it isn't working by default on my wiki.
[...]
Well, the greek basically is a way to tell the web server to rewrite
the request before sending a response *if* the file is missing.
Those JS URLs are a local hack at individual wikis and not part of a
default mediawiki install (i think! at least last I checked) so I'm
not surprised they don't work out of the box.
