The last vertical bar is not optional. Without it the right is
interpreted as alt/caption text and NOT as a formating option.  You
need
[[image:test.png|right|]]

This might have worked somewhat differently in earlier versions of
MediaWiki.  It seems to be somewhat "under construction." In fact the
article about extended image syntax in the Wikipedia doesn't do alt
text/captions exactly as it says it should in all cases.

I'm pretty sure that image resizing, whether for thumbnails or in
general, requires either the GD library or the ImageMagick external
program. ImageMagick may not work on all platforms. On my 1.3.x
installation on Linux, I've got the following lines in my
LocalSettings.php file:

$wgUseImageResize = true;
$wgUseImageMagick = true;
$wgImageMagickConvertCommand = "/usr/bin/convert";
