But back to the question.
Custom titles are not enabled for the user here.
So I assume Rick edited the member in the control panel for custom title and placed html code to reference the graphic, that works. Regardless if the permission for the group is set to 0 characters for custom titles.
As a Admin goto cp>> Member Management
At least it did in classic.
Using the br tag you could also add multiple lines.
I don't believe a visitor can add html code to a custom title even if you expand it to 1000 characters.
I have not tried this since the classic version so....
