Some Homepage things and new images?

I was just rooting around the ads side of Habbohotel and found this link:

http://ads.habbohotel.co.uk/max/adjs.php?n=a65b6b4d

Now if you click on it, theres a load of code, i found in this code this link:

http://www.habbohotel.com/habbo/en/community/chicago/

I wonder what thats doing there? :o

I found this image too, in all that coding:

This link intriegued me the most, as it seems it hasnt been seen on the site before, therefore does that mean its a new feature yet to be revealed to the US public? Interesant!
