Tom Bricker has a large selection of photos you can download free, as well as other photos that you can only purchase. He has AMAZING photos, and he probably sells tons of pics. Here is his website with his photo usage policy.
************************************
part of his policy:
"Many photographers ardently attempt to prevent others from using their images. That is not my philosophy towards photography. I began taking photos with the purpose of sharing them with others, and my goal always has been to make as many people happy through my Disney photos as possible.
I welcome and encourage others to download my photos for their personal use, to share my photos on social networks like Facebook, Twitter, Pinterest, and Google+, or on their non-commercial blogs or websites. There is no charge for such usage and you do not need prior approval from me. In fact, I would like to thank you if you share my photos!
Most photos on the blog can be easily downloaded and used, but the easiest way to use my photos is go to my Flickr page and grab the HTML or download the full size images and upload them on your own blog or social media account. You may notice that not all of my photos are on Flickr–many of them are, but there are some that are only available to purchase as prints. Keeping some photos exclusive to SmugMug provides a way for those who enjoy it to support my photography while still leaving thousands of free photos for those who don’t want to spend money on prints. Fair enough?
With that said, I do have a couple of requirements and limitations:"

edited to add--I guess I can't link to a website. Google Tom Bricker or Disney Tourist Blog.
