I get the photos that I need for my classes by taking own pictures. And if I need to use photos from other people I will cite the source and not use the photo in a vulgar way.
If someone is using my images for a project then I expect them to cite the source (me) and not use it in a vulgar way.
My logo is my last name (Adhami) in all caps followed by a picture of a simple camera. My logo was easy to design because of how simple it is.
