I typically get photos that I need for school from Google. I never contact the owner of the photo, though I sometimes give credit in the form of citations. However, if someone were to use my photos for a project, I would probably expect some sort of credit. For my logo, I just played around in Adobe Fireworks with my first/last initial (F), trying to see if I could make it into something that slightly resembled a logo. It was very easy for me to finish once I started, but it was hard at first coming up with an idea.
