When I need a photo for a class I go to google and search for what I need. I never contact the owner of the photo, but I always give them credit in the form of a link to the photo. If someone used my images for a class project I would expect them to keep my logo on the image and provide a link to my website. My logo is my initials inside the outline of a camera with the word photography under it. The easiest part about designing my logo was stretching the top part of the “B” so that it touched the “O”.
