None of the following lines display any image on my wiki page. I've uploaded the image and can see it full size by saying [[Image:100_0170.JPG]]. But when using the "thumb" option, it will only display the image if the px number is at least as large as the original image. Otherwise it doesn't show up and just displays a red X. Is there anything I'm doing wrong? Is this a bug? [[Image:100_0170.JPG|thumb|none|191px|left|Sample thumbnail]] [[Image:100_0170.JPG|191px|]]
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";

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 Files/TSW/Apache2/htdocs/mediawiki/images/thumb/a/ad/100_0170.JPG/191px-100_0170.JPG, referer: 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($srcPath) . // Coalesce is needed to scale animated GIFs properly (bug 1017). ' -coalesce ' . // For the -resize option a "!" is needed to force exact size, // or ImageMagick may decide your ratio is wrong and slice off // a pixel. " -thumbnail " . wfEscapeShellArg( "{$physicalWidth}x{$physicalHeight}!" ) . " -depth 8 $sharpen " . wfEscapeShellArg($dstPath) " 2>&1"; /*end modified*/
