a college professor told you it was unnecessary to cite references?
I'd stick your credits on each slide, in small font (10pt text even) on the bottom. JUST so you have them there.
Citing references and resources isn't just about making profit. its acknowledging that the information you're using didn't come from you -- it came from someone elses work.
As for the presentation itself... Most presentations include VERY few words, and more pictures. Have 9 slides worth of images and your title slide. Or maybe a bullet point or 3 on each one, plus an image or 2.
I can't help you out with any images really until you ask for something a bit more specific. I've got a few gigs of bp pictures that i can sort though.
