Here is a screenshot I took of the tightrope puzzle. You can use, edit, whatever you want with it. There should be an easier way to submit stuff for the site. I had to sign up here, then upload the cap to my site, since you can't just upload an image. This is really a lame way to do things. I'm surprised you have half the content you do. Having an easy and simple contribution process would probably get you more content quicker... I doubt I'll do it again.
