rtMedia Gallery Widget

I just purchased the gallery widget and so far things are ok, BUT i have a question, how do you set the gallery widget OR rtMedia to display the thumbnails from users on users wall only? Right now if i upload a photo it shows up on everybody’s wall in thumbnail form. How do i set this to display ONLY what each user uploads, uploads to their wall only, like twitter and Facebook. Can this be done with CSS? or something simple.

Thank you for your time. Andrew
