IMG tags are disabled here so you can't put an image directly within your post.
You can only use a URL to link to an image.
URL syntax is as follows:
CoH Homepage
Using the above code will look like this:
CoH Homepage
To link to an image, simply use the image's URL, like I did in my signature.
When you hit reply or make a new post, there should be a box under where you enter text that says "Instant UBB codes". Very first one in that box is "URL". That's the easiest way to do it. Conversely, replace the { } with [ ]: {url=www.urlhere.com}enter text here{/url}

The only images you make a link of are the smilies. 
You need to have a space after the ] and before the smiley.

Biggest Troll on the forums? I'll give you a hint:
How do I make a url or image link? The one where you bind the word to the picture so the word is green and you can click it. Every time I try it just displays the thing I copied from the search bar and its not clickable and not bound to a word. :/
