It's a cool picture but you haven't applied it correctly.
You have done this:
[url](<!-- m --><a class="postlink" href="https://lh5.googleusercontent.com/-2kCbWOCenvY/ToHyAdw6WZI/AAAAAAAAAJA/JrgzsMRmT6w/arena.jpg">https://lh5.googleusercontent.com/-2kCb ... /arena.jpg</a><!-- m --> )[/url]
You need to do this mate:
[img](<!-- m --><a class="postlink" href="https://lh5.googleusercontent.com/-2kCbWOCenvY/ToHyAdw6WZI/AAAAAAAAAJA/JrgzsMRmT6w/arena.jpg">https://lh5.googleusercontent.com/-2kCb ... /arena.jpg</a><!-- m -->)[/img]
and it should work, if you copy and past it take the brackets () out
