// BEGIN: MediaWiki interface button definition for Duesentrieb's image tools:
// "Check usage", "User image gallery", "Orphaned images of user" and 
// "Untagged images of user".
// If you are located at an "Image:" you get the "check usage" tab, if you
// are at a "User:" page you get the "gallery", "orphans" and "untagged" tab.
// If you are on other pages these tabs do not get shown. These functions are
// enabled in Wikimedia Commons by default via [[Mediawiki:Monobook.js]] and
// its local language subpages.
// This script has been tested with Konqueror 3.5 and Firefox 1.5 and other
// browsers including Opera and Internet Explorer have been reported to work
// as well. If you enhance or change this template please test it previous to
// editing here in your local monobook.js with as many as possible browsers
// (in order not to clash with the function names here change in your local
// monobook.js all "global_" to "local_").
// Be aware that the global JavaScripts do not get updated by the Wikimedia
// servers that fast after saving them.

// written by Dbenbenn, Avatar, Duesentrieb and Arnomane

// Switch for people that don't want the extra tabs.
