Since this spot look hasnt been changed for ages I think it's time to have some changes. Anyway I hope at least someone try suggest they wishes of either icon, banner or both to be fair.

Here are the guidelines:

Icons must be square like 100x100, 200x200 etc...
Banners need to be 800x100 px or a size that scales down to that. Mind the spot title, which is 130px long and 40px high, and will cover up whatever's in the lower right-hand corner of your banner.
