We have some problems with users that links to extremly large images for their avatar. We're using an extended version of 2.1.6 at the moment.
I've introduced a new configuration parameter called avatar.allow.external.url. If this is set to false, then the user will no be able to link to an external image. I've also implemented support for this in classes, and templates.
Is this something you think we should add into JForum?
It can be turned on by default, so that it normally will appear as it does today?
It would be great if you can take a look, and see if I've commited the way you like it, and if I should do anything different next time. Since I'm new on the project I might have broken som "interal rules".
I had to comment out line 97 in UserCommon.java in order to remove a bug introduced by someone else. We should re-introduce this when the bug is fixed. See: https://coderanch.com/t/576733
