there is always a possibility that you will be taking photos that are copyrighted. You can always contact the owner of the website that you want to take a picture from and ask permission. if he says yes, make sure you get an email confirming this. there are also many websites that sell pictures. the sight i use a lot is www.istockphoto.com
they literally have millions of pictures on the site and i'm sure you will find something you like.
