When I need photos for a class, I usually go on Google. Normally I do not contact the owner of a photo. If it is a written project, then yes. If not, then no. I normally give credit to the author. I do not expect them to give me credit but I would like it. My logo contains my initials (ESK). My logo was not very hard to make. It was easy to create since it was a star. It was some what difficult when I had to pick a color that goes with both light and dark backgrounds.
