bbpress Upload Images

I want participants (bbpress roll) to be able to upload images on a topic in the forum. I have used the TinyMCE and have the upload media button showing and it allows you to select a file to upload, however does not upload it.

I used Capability Manager to give them to right to upload media as I thought this would be enough.
