Help me!! How to put image for this area?

You can't upload a banner to your profile. Everyone has the same blue area.

You can only upload a banner to a club that you personally created. There will be an "edit club" button underneath the banner box on the right-hand side of the page.

I don't think you can change the banner unless you created the club, but other than that I have no idea.

As far as I know you can only change a banner if it's on a club you created but not on your profile page. Hope this helped :)

The banner? You go to the club and go to edit club. It has to be a club that you had originally made.
