i don't really get how to put a icon and banner can someone help me?

If you created the club under the banner on the right hand side there will be an edit club button. Click that. At the very bottom there will be a place to upload a banner and icon.

To put an icon and banner for your club, look under your current banner and it should say edit club. Click edit club. Then, scroll down until you see suggest a banner and icon. There, you upload the litrato that you want to turn into your icon or banner. Here's my answer!!

go to edit club after you make it scroll down and you'll see to spots where you can download a banner and another for your icon the banner must be 800x100 if anymore of less it won't look very good the icon you can be a bit madami flexible on standard is 100x100 but i think you could still have a good one if you went up to 500x500 they would just edit the size themselves to make it look good I hope i helped =)
