Guild Wars 2

how do i put a picture in my post?

and why does jpg not work? only png? how to convert?

to convert (on windows) open the screenshot in ms paint, save as, and select png as the file format.

Alternative you can use an external image hosting software and link to it from here. Use this list for finding your favorite service for it: http://en.wikipedia.org/wiki/List_of_photo_sharing_websites

jpegs work fine in my experience, I’m always posting in game screenshots and they are jpeg files.

Also, when you go to post or reply to a thread there is an option highlighted in red ‘More posting & formatting options…’ Click this and it will give you an option to attach a picture, this way you don’t need to link to an external hosting site.
