I'll just try to answer this in the simplest way I can think of.
To make your own banner and شبیہ just use editing programs such as Photoshop, PhotoScape یا Gimp یا any other that could help but آپ probably already knew this.
To لوڈ اپ a new شبیہ and banner for the spot, just go to the spot آپ made and follow the instructions that
link gives you. I hope this helps! :D
I also hope I explained how to do this well, just please let me know if I didn't.
