Hello again @P.S2022 - Unfortunately there isn’t much else you can do to add pictures in your forum profile but you can add a link to your main website profile which will provide a link through to all the pics you have there, for people to view.
And of course, in a topic, such as an introduction thread you can upload images there too. If you create an intro post, you could add the link to that in your forum profile too as you’ve done with another thread.
Here are the instructions for adding a link in your profile.
Hope that helps, all the best, Vanessa
