426732 Picture Gallery Censorship for WP Site

I need someone to figure out how to censor our picture galleries on our Word Press site. I have a template very similar to [login to view URL] and would like to build the same functionality where some X rated photos are censored by a color shape (in their case a star), however if you click on the picture, you can view it uncensored see example here: [login to view URL] In addition, I would like to build in a function where all censorship is removed for users who login to their account. Let me know if you need more clarification or submit your bid and the solution. Thank you.
