How can the admin (or other user with admin privileges) modify another user's picture/avatar?

The only way that I've found of doing this is attaching a file to the user page and editing the XWiki.XWikiUsers "avatar" class item manually. It looks like the regular avatar upload page doesn't work properly for anyone but the user in question.

I guess there's a bug in changeavatar.vm, you must add: #template("xwikivars.vm") at the start of that file, so that $hasAdmin is initialized. -- Sergiu Dumitriu http://purl.org/net/sergiu/
