This plugin is tested only with BP 1.6.2 and WordPress 3.5, and is not meant to be backwards compatible! If you’re running an older version of WordPress, use Vernon’s original plugin <a href="https://wordpress.org/extend/plugins/buddypress-default-group-avatar/" rel="ugc">BuddyPress Group Default Avatar</a>
Allows specifying the URL of an image to use as the BuddyPress default group avatar. This makes it easy to distinguish groups from members who are using the mystery man default user avatar.
It works in all situations (activity stream, groups, forums, directory, etc). Upload your image to somewhere within your theme and drop the full URL in the options screen.
If you had <a href="https://wordpress.org/extend/plugins/buddypress-default-group-avatar/" rel="ugc">BuddyPress Group Default Avatar</a> previously installed, this plugin will use the avatar set in that plugin. Otherwise it’s bundled with a default avatar for groups (see screenshots).
Not tested on multisite/network install yet (please confirm if it’s working!).

BuddyPress Default Group Avatar

Adds a default group avatar to BuddyPress without disabling Gravatars for users.

Some plugins and themes replace the default jQuery library that comes bundled with WordPress with another version, 
typically from the Google AJAX CDN. This is generally bad practice, since many other plugins and themes rely on and 
expect that the WordPress-bundled jQuery version is being loaded.
Also, typically the alternative jQuery library being loaded is not executed in the jQuery noConflict mode, which tend 
to cause conflicts with other JavaScript frameworks, like Prototype and MooTools.
This plugin simply restores the version of jQuery being loaded to the one that comes bundled with WordPress. It only 
does this if jQuery is already in the WordPress scripts queue, and won’t do anything otherwise.

Restore jQuery

Restore the loaded jQuery library to the version bundled with WordPress.
