The Banner Guidelines can be found on our Poker Ad page ("Banner Ads" tab and specify the limitations for each banner size.
This is done to ensure PokerDIY loads quickly for all users (not everyone is on a super-fast internet connection!)
For example, the 125*125 banners on the right must be under 20kb in file-size and have a maximum of 3 animated frames.
The reason for the limitation on the number of animated frames is that we pride ourselves on PokerDIY's clean/non-flashy look. We know how irritating it is to be bombarded with flashing colors and "CLICK HERE" type ads and we don't want to see them on PokerDIY. All ads that get uploaded go through an approval phase - please check that your banner ads adhere to these guidelines.
