Regarding your image questions:
1. Try using www.creativecommons.org/# to search for your images. They will find images that are licensed under Creative Commons, meaning in most instances they are free as long as you credit the author or other items, which they tell you up front.
2. In order to keep images from being fuzzy,
when you decide what page template you are going to use, roll your cursor over the Media window. You should get a tool tip that tells you the max dimensions for the media. Keep in mind you can resample down and the image will maintain clarity. If you try to enlarge an image, you will begin to get artifacting and the image will be come fuzzy looking.
Hope this helps. If you have any questions, feel free to contact me: craig.jackson@rcu.msstate.edu
