borders on iframes

OK, I'm nitpicking here. But when a screenschot or video pops up it doesn't have a border. Therefore it blends in with the main site and not really pops out. I suggest a 1 px black border or something like that.

Forums: 

thicker, thinner, darker, lighter? you're always welcome to nitpick ;)

EDIT: i thought about you comment and figured that you where referring to something else than the border around the images.
when a image or video pups up, the whole site should go black. isn't that the case for you or is it not what you had in mind?

Ah, that makes sense, I am using google chromium and the whole site doesn't go black. Here is an example how it looks, top is current, bottom part is a suggestion. http://i.imgur.com/qvGqF.png
