You want to enable image resizing in LocalSettings.php
$wgUseImageResize = true;

That should use GD for resizing. Eventually install imagemagick and add:
$wgUseImageMagick = true;
$wgImageMagickConvertCommand = "/usr/bin/convert";

Hey Ashar. I installed ImageMagick and changed the approproate lines in LocalSettings.php to enable it. But
still have the same result.

I can see that the images are not being generated in the "images" subfolders. As a result I see the following errors in the
error log:

[Thu Jul 14 09:18:59 2005] [error] [client 132.224.125.91] File does not exist: C:/Program

http://132.228.122.89/mediawiki/index.php/Brad%27s_Playground

My LocalSettings.php looks like this:

$wgEnableUploads = true;
$wgUseImageResize = true;
$wgUseImageMagick = true;

$wgImageMagickConvertCommand = "C:\\Program Files\\imagemagick-6.2.3-q16\\convert.exe";

I' ve modified the file includes/media/Bitmap.php. Now the thumbnailing works fine. Especially redirect from stderr output to stdoutput at the end of the command makes the command not working. The command tries to create a file "2>&1". Also the function wfEscapeShellArg() which escapes the $wgImageMagickConvertCommand, $srcPath and $dstPath makes the command not working.

Below i've my solution for the problem.

/*modified by kpf 16.01.2008*/

$cmd  =  $wgImageMagickConvertCommand .
        " {$quality} -background white -size {$physicalWidth} ".
        $srcPath .
        // Coalesce is needed to scale animated GIFs properly (bug 1017).
        ' -coalesce ' .
        // For the -resize option a "!" is needed to force exact size,
        // or ImageMagick may decide your ratio is wrong and slice off
        // a pixel.
        " -thumbnail " . wfEscapeShellArg( "{$physicalWidth}x{$physicalHeight}!" ) .
        " -depth 8 $sharpen " .
        $dstPath;

/*

$cmd  =  wfEscapeShellArg($wgImageMagickConvertCommand) .
        " {$quality} -background white -size {$physicalWidth} ".
        wfEscapeShellArg($srcPath) .

        " -thumbnail " . wfEscapeShellArg( "{$physicalWidth}x{$physicalHeight}!" ) .
        " -depth 8 $sharpen " .
        wfEscapeShellArg($dstPath)  " 2>&1";
