Well here is lil introduction to posting image.
When u have your writing window in forum opened look for a icon caled "Host an image" - press it - choose "browse" - find your image in pc and press "open" - press "host it" ( u may change size of picture before u press host it ) - now u will see 3 webadresses called "Thumbnail" "image" "image URL" - so just simply copy WHOLE adress from "image" into chat window and THATS IT
For any issues pm/whisper me in game. And there will be some issues am sure, because am a idiotic poster
