What is the syntax for showing an externally hosted image in a media wiki page?  The media wiki help page doesn't seem to cover that scenario.I've tried several things that don't work:[http://example.com/image.jpg][[File:http://example.com/image.jpg]]<img src=http://example.com/image.jpg>
How do you hot link an external image from a Media Wiki site?
images;mediawiki;hotlinking
Your example [http://example.com/image.jpg] is correct.You will need to enable this by setting $wgAllowExternalImages to true in your configuration file. The default is false. Optionally, you can set $wgAllowExternalImagesFrom to allow exceptions while $wgAllowExternalImages remains set to false. You can also use $wgEnableImageWhitelist to allow exceptions based upon regular expressions.You will likely need to copy the appropriate line from DefaultSettings.php to LocalSettings.php.Here are some links (in order):http://www.mediawiki.org/wiki/Manual:LocalSettings.phphttp://www.mediawiki.org/wiki/Manual:Configuration_settingshttp://www.mediawiki.org/wiki/Manual:$wgAllowExternalImageshttp://www.mediawiki.org/wiki/Manual:$wgAllowExternalImagesFromhttp://www.mediawiki.org/wiki/Manual:$wgEnableImageWhitelist
