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.

Hello,
At the moment i am buiding a intranet using an instance of the MediaWiki.
There are a few issues I cannot resolve though. Any help would be
appreciated!
ImageMagic:
I cannot get te resizing of Images to work. I have done the following:
1)Installed a version of ImageMagic in directory C:\Program
Files\ImageMagick-6.1.8-Q8 (using
ImageMagick-6.1.8-Q8-windows-static.exe);
The environment variable PATH is set correctly
2)Made a copy of convert.exe (ImageMagic) to c:\ (To avoid problems
with the space in "Program Files" in the path to the original
convert.exe);
C:\convert.exe works from the command shell, I checked that.
3)Placed a copy of php_imagick.dll in C:\EasyPHP\php\extensions
4) added extension=php_imagick.dll to php.ini in the C:\Windows
directory
5)Placed a copy of ImageMagickObject.dll in the C:\WINDOWS\system32
directory
6) Changed LocalSettings.php to:
<snip>
## To enable image uploads, make sure the 'images' directory
## is writable, then uncomment this:
$wgDisableUploads = false;
$wgUseImageResize = true;
$wgUseImageMagick = true;
$wgImageMagickConvertCommand = "C:\convert.exe";
</snip>
When I Upload an Image (BenR.jpg 1022 x 1363 pixels, deliberatly big
in size) through the [upload] link of the wiki, the image itself loads
correctly, but the resized one (to fit on the image's info page) does
not appear. I get a "broken picture" frame from my browser instead, as
well as 2 errors rendered into the HTML of the page:

When cleaned they read:

This left me at a loss as to what is going on. The error log of Apache
shows another strange thing (apart from the error from convert.exe or
is it PHP's?)

I'm guessing that the Apache-error "invalid Filename" induces some
kind of illegal filename to begin with. When that is offered to
convert.exe or to convert.exe via PHP things go wrong.
-- The documentation on ImageMagic is scarce on the Internet
-- I am using the wiki in the Dutch (nl) language, hence the
'speciaal:' en 'afbeelding:' in the Apache log. 'Afbeelding:'
meaning
'Image', and 'speciaal', well I'm not sure ;-)
-- I do not have a trailing slash in my DocumentRoot
I am using
MediaWIki mediawiki-1.4beta3
easyphp1-7 (with apache 1.3.27, PHP 4.3.3. Mysql 4.0.15, phpadmin 2.5.3)
Windows XP (SP2) Home edition 1GB RAM
I would be very gratefull for any answers or suggestions!
