Grey box instead of pictures on frontpage

I’ve recently bought a domain and webhotel from UnoEuro, and used their 1-click installer to get WordPress. I exported everything from https://www.politik.spirmedia.dk to the new website, https://www.detpolitik.dk.
After changing URL on a few pictures, I saw that they only showed a gray box. If I remove the picture, it says theres no picture available.

I’m using the theme Original Premium News 1.2.0 by WooThemes, and WP version 3.2.1. I tried to put wp-content/uploads into the media settings, but nothing. Then I found a WPMedia map. Apparently it was pretty empty, so I took all pictures I had uploaded, and dragged in there.

I can’t find any theme folder, so can’t see if a setting or url is set to 777, as it was stated it had to be in another post.

I even tried to clear every thing. Stripped off of everything and make a new post with no imports at all. That didn’t even work. Did what I had to do, but yet a silly gray box.

I’m in really big need of help.
Any ideas or help is greatly appreciated!

Best regards, Jonas.
