Use site avatar and not gravatar for RECENT GLOBAL POSTS WIDGET

Hello, i am using the RECENT GLOBAL POSTS WIDGET , together with a plugin called User Profile Picture that lets me set an image as a profile picture for users.
Is it not possible to have your recent global posts widget that the used profile image and show as avatar, rather then trying to pull a gravatar thats not there. ?
