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!).

Are you tired of manually configuring a default featured image each time you publish a page, post, or custom post type? Do you desire a default featured image to automatically serve as a thumbnail whenever you publish or update your post/page?
Look no further!
This plugin provides a convenient solution to set a default thumbnail image effortlessly for all your posts, pages, or custom post types. Select or upload any image from your media library with ease.
Access the settings via the WordPress Dashboard under Settings => “SNY Auto Featured Image” (admin menu).
Quick Setup:
<ul>
<li>Choose/upload an image from the media library.</li>
<li>Specify categories.</li>
<li>Define the post types.</li>
</ul>
Please note that this plugin automatically assigns a thumbnail when a post is published or modified, but only if the post lacks a featured image.

SNY Auto Featured Image

Automatically set a default featured image for posts, pages, or custom post types when none is assigned.
