[Mediawiki-l] problems getting ImageMagic to work

[Ralph]

I had problems running ImageMagick on Windows XP too.  I also go this 
error and found that the problem was in the php when it called the 
convert EXE.  It was using the wrong quoting character.  I am using 
1.3.7, and found that I had to change Image.php

in function: function createThumb( $width ):
originally:
                $cmd  =  $wgImageMagickConvertCommand .
                    " -quality 85 -background white -geometry {$width} ".
                    escapeshellarg($this->imagePath) . " " .
                    escapeshellarg($thumbPath);

to:
                $cmd  =  $wgImageMagickConvertCommand .
                    " -quality 85 -background white -geometry {$width} ".
                    "\"$this->imagePath\" \"$thumbPath\"";

I'd give a diff, but I also later changed image.php to support a limited 
image gallery I was working on, which is unrelated to this fix.  Try 
this and let me know if it works.
