Photographs on this site come from Wikimedia Commons, and every one of them carries a licence that allows commercial use. Where the photographer asked to be named, you will see the name here and again in the caption on the page the photo sits on. If you took one of these pictures and want the credit changed, or the picture taken down, call and it is done the same business day.
Some of these have been enlarged and sharpened so they hold up at the size they run here. Nothing has been added to a picture and nothing has been taken out of one: no house, no car, no person, no sky. The last column says which ones were touched, because the licences ask us to say so.
