Anytime someone takes a pic or puts words on paper they acopyright to that. You can't just take an image off the web and use it unless the person has put it in the public domain. I'm sure someone has put a picture of that sign in the public domain and if you do a search you could find it.
That being said you can go to fotolia and get the image for a buck. I do that alot when I need an image. I figure a buck is a small price to pay to the person who has taken the picture. Here is a link to fotolia for "vegas sign"

Honestly though, I don't know if it is legal to take a picture of the sign and use if for commercial purposes. I wouldn't expect that I could go take a picture of the golden arches and use that in a website where I am going to make money from something dealing with fast food.
Nice site by the way :gn:
