|Thumbnail settings: $wgThumbnailScriptPath|
|Path to thumb.php, if you want thumbnail generation on the fly.
|Introduced in version:||1.5.0|
|Removed in version:||still in use|
|Allowed values:||(filesystem path) or false|
|Other settings: Alphabetical | By function|
Give a path here to use thumb.php for thumbnail generation on client request, instead of generating them on render and outputting a static URL. This is necessary if some of your apache servers don't have read/write access to the thumbnail path.
If you want to use this feature, you would set this as follows:
$wgThumbnailScriptPath = "$wgScriptPath/thumb.php";
