i am looking for a plugin that allows only a specific group of user to see pictures or videos. Other users ( probably non paying) would be able to see the conversation but not the pictures and the videos.
You could mostly hide them with a theme component. The links would still be in the browser if someone had the energy to find them, but it’d probably be a big enough hassle that people who wanted to participate would still pay.
There are examples of how to do for members of a group, so you’d do something like hide all of the <img> tags and un-hide them for people who weren’t in the “good” group.
