How to add Multisite featured post images on users activity stream?

Hello guys!!!

I'm running a BuddyPress+Wordpress Multisite project here... The multisite installation runs some video sites with a YT importer plugin. This plugin imports YT videos with thumbs inserted as featured images. I want these images to appear on users's activity stream.

Is there a way to do that?

Remembering that the plugin imports YT videos as normal posts, not custom post type, it just set the post as vídeo post.
