Error Creating Thumbnail: Unable To Save Thumbnail To Destination
in MW1.19.2 is too low for SVG thumbnail rendering. The Error message mediawiki images not showing produced by a value too low is far too obtuse: Error creating thumbnail: ERROR: meta.c (179): wmf_header_read: this isn't a

Setting $wgMaxShellMemory to 300000 FIXED IT. (Thanks folks on Mediawiki-l for the tip! I would never have thought of this!) Caution: This is LINUX only! Won't work with POSIX like systems e.g. FreeBSD[edit] Hi everyone, the function wfShellExec()[1]checks OS for "Linux" before using localsettings.php not found "ulimit4.sh", so for example FreeBSD won't use any ulimit here. This will fail sooner or later. Someone[tm] should[tm] create a patch for ulimit4.sh and wfShellExec() to enable ulimits for any POSIX aware operating system having a /bin/sh. Bug report will follow. --Rabe (talk) 10:06, 26 April 2013 (UTC) I patched this for my system and verified it by getting a memory allocation error now: Fehler beim Erstellen des Vorschaubildes: convert: memory allocation failed `/data/www/wiki.*****.org/secure/images/1/1b/FreeBSD_System_verschluesseln_mit_geli(8)_Diagramm.svg' @ error/svg.c/ReadSVGImage/2968. convert: no images defined `PNG:/data/www/wiki.*****.org/secure/images/temp/transform_28149c237e88-1.png' @ error/convert.c/ConvertImageCommand/3078. The Community should check my patches (especially on Linux), see Bug 47781.

Jun22,2009,8:21AM Post #1 of 5 (9358 views) Permalink Error creating thumbnail: Invalid thumbnail parameters I've just uploaded a largish GIF image to my wiki and I'm getting an error that http://www.gossamer-threads.com/lists/wiki/mediawiki/169430 says: "Error creating thumbnail: Invalid thumbnail parameters" I say largish but it's not http://arnulf.us/Error_creating_thumbnail:_Invalid_thumbnail_parameters really that big a file (4,865 by 3,300 pixels, 410 KB). The file uploads without other problem and I was able to manually create a thumbnail at the command line (on the server) using ImageMagick (which is what MW is set to use). I couldn't find the phrase "Invalid thumbnail parameters" anywhere on the MediaWiki error creating site. It's not clear from the error what "thumbnail parameters" might be "invalid". Any suggestions what might need to be fixed or adjusted?

I also changed the $wgMaxImageArea variable to something larger than the default value (I set it to 64,000,000 which is well over the image area for the file in question, which measures 16,054,500). The error message I get now is slightly different: Error creating thumbnail: convert: Memory allocation failed `/path/to/wiki/images/6/69/Countries_11x17.gif'. convert: miss
