It is very easy to put in a screenshot^^ Simply take a screenshot of the place in the map and go to
http://tinypic.com/^There you see the select file and upload now botten^^.
You then have two links you can use! one is
IMG Code for Forums & Message Boards <- This is for Spoiler pictures! So people have to click the spoiler butten to see the picture! You use ->[ spoiler=][/spoiler ] <- IMG picture. *No space inbetween the ]'s at the end!
Direct Link for Layouts<- Direct link/picture, is for all to see the picture when you press in your post! You can use ->[ img][/img ] <- And Direct picture so people don't press anything^^
I hope this helps^^ If not. Do tell if i messed things to much op o.e' It's like when you color your words on posts^^
