First of all apologize if this is not in the right thread.

I am starting up a sports website covering collegiate sports. I can't afford to license photos for official use on my website yet. I want to stay legal on my website so what are my options?

I can create a lot of graphics myself to use but it would be ideal to use action photos. What photos can I use legally or within fair use? Can I use logos etc?

The whole issue of fair use is confusing. I would really like to use action photos. As of now I have been gathering photos on flickr that are under creative commons and do not have rights reserved. These photos will work but they are not the close up action shots. Any suggestions? Any literature I should read?
