Tournament Banner and Max Allowed Users and AutoAccept

I have three questions – maybe someone needed this info and managed to find out answears or maybe Zorz knows answears:

1. Tournament Page sets Tournament ICON and BANNER using function from template. It will set ICON and BANNER from files you provided for chosen GAME. How can i Change BANNER to make it custom for each single Tournament – make the choice of Banner separate from Chosen GAME? As i would like to have different Banners for Different Tournament for 1 Game.

2. Whats MAXIMUM SUPPORTED number of users that can participate in KNOCK OUT Torunament? I know it works for 30 for sure, but i would like to host Tournament for 256 Players – will it work?

3. Can You Make Auto Accept Function for Tournaments Seperate Option for EACH single Tourney instead of full page? I would like to have it on for some Tourneys and OFF for other.

Best Regards
