/* On [[Special:Upload|Upload]] page this script allows you to preview Summary field using [[AJAX]].
Without the script you have to first upload image and then check how your description look like. See why: [[:mediazilla:2537]], comment #6. The script is using [{{SERVER}}/skins-1.5/common/preview.js preview.js] which is a part of [[:mw:Manual:Live preview|Live preview]] which is not currently used by Mediawiki.
Installation: add to [[Special:Mypage/monobook.js|your monobook.js]]
