Changing the background of the profile page

Hi. How can I change the default background shown in the user profile page:

?

Thanks.

You may be able to do something with the profile customizer and set permissions.

yoursite.com/m/profile_customize/administration/background/1

You will need the module installed of course, this may or may not work, and check.

I have not tested this.
