I get photos from the Internet or I take them myself. I do not contact the owner but I do show the URL or include the name of the photographer. No, I don’t always give credit but I do as much as I can. I would expect them to not crop out my logo or at least give me some credit. My logo is a camera with my name spiraled in the middle. The difficult part about making my logo was spelling our company name “Connors Photography” letter by letter and twisting it.
