Just what the doctor ordered!http://www.cgtextures.com/The landscape pics are very large and high quality. They have quite a few building scenes too. Just hunt around the site. Lots of good pics there.
I have found that pictures in magazines of city and/or country scenes can also work if he has the ability to blow them up to a larger size....chuck
Try this site, they are in business and sell backdrop scenic pics. You can get an idea or perhaps copy and print something there, they do it in all scales, just search the site!

You might try some Photography Stock Houses and see what they have available . There is usually a fee but generally the quality is Great .
I have a friend that own's a print shop. He told me that he can print pictures on wallpaper that I could use as my background. He said it wouldn't cost much if I gave him the pictures for the background to scan in his computer and then print. My question is, is there a place to go go get some manufactoring pics or mountain pics I can copy and give him? thanks
