I am looking for something like this:
Looking I found this addon for background: https://xenforo.com/community/resources/profile-background-image-customization-themescorp-com.4246/ but I have not found how put an image as header in profile page.
That forum includes an option for change header in the same page (more confortable):
I have also found other sites with similar options but i not found addon for this.
If you know of something, I will be very grateful.
