Get Marwood and I

I recently noticed the link to display a user’s images in the profile is now visible even though the user hasn’t uploaded any images. 

Is there a way to disable this link if there are no images?
 

Here is the user in question. He would like a different title under his avatar. we are tryin go to determine who can change this, and how to make the change.
 

Hi,
What is the official name for the title located underneath the avatar picture in a forum post?
How can that be changed? And who can change this?
 
Thanks!
