Help creating server list banner

Hey guys First off I have looked around maybe not good enough duno :P
Anyhow how do i place my custom server list baner in game at server list?

Also question bout new server files, do they fix the errored items, more deco items on npc?, and champ spawns thnx for any replys!:bandit:

If you are using the 1.3 repack, just copy & paste the link to the banner into the S game.server_screenshot_url: line. The screenshot must be uploaded on your apache server.

Thnx alot soul you the man. Btw what is best resolution for the banner?
