BuddyPress.org

Thanks @Chouf1 it looks like a good lead – but unless I pay for help its beyond my minimal skill levels to implement it..
I guess I could start be looking at functions.php and wp-includes/kses.php ?
However Im beginning to think that this is not just a question of getting html in
but also of displaying pictures or other media in an extended profile field on the profile page.
I used a plugin which seemed to keep the html intact – but nothing showed up in the profile.

I still cant figure why this isnt a straight forward thing to do on the profile page as it is easy enough to use Tinymce to add media in a post?
