During my short lived time here on this forum, I have posted a few pictures. Now I use the attach option and choose the .png or what other file I want to show. However I have noticed that those only show up(at least for me) when I am logged in. Otherwise it just looks like I am a crazy dude talking to a wall. However I notice that there must be another way to post an image because I often browse these forums without having been signed in and actually see pictures. So my question is:How do you post pictures so that anyone can see them?
