To make the banner toi click éditer and then there will be an option to add a picture and a banner. I usually just find a picture that fits the banner instead of taking a bunch of photos and making one. But its your choice.
Oh I don't think that's an option toi just have to find a banner that fits perfectly. But a really great trick is say your club is a movie (example: étoile, star Wars ou something) toi could go to Google and type in étoile, star Wars Banner and images would montrer up. It worked for me.
