Arc'd earth shape site header with landmarks

I have an idea for a website header graphic, but I’m having trouble conveying it to my web designer. I picture a rounded or arc’d line representing the surface of the earth, with famous landmarks from left to right denoting cities around the world. I know I’ve seen this type of look somewhere before, but I can’t recall where or when… Does anyone here know what I mean? What do you call that type of graphic? Or where can I find some examples, etc? Thanks

Any of [/source/basic/?#1f6ce5c6"]these](http://www.istockphoto.com/search/text/cities_of_the_earth/filetypes/[7) help?

Yes, they do! Actually, I did find a couple of these stock images in my hunt, but not all of them. I think I’ll have enough to convey the idea to the designer now though. Thanks for your help!
