This list will grow as time allows me to work on it. Most of the time when making a book trailer I'll have about three stock images and the rest will be free. I always try to use my book cover, and maybe a couple of paid for images for the models that I use on the book cover. I'm pretty sure it's best to buy a second smaller image for those book trailers. Here is a list of my favorite stock sites. If you add some more stock sites I'll edit this one with your suggestions and this will be a Sticky in time. Always check several sites when looking for an image, often the same photographer will have the same image on another site for a cheaper price, or they may even have a different image of the same model. I'm going to blog about Stock sites, a link will be here at some point. http://www.bigstockphoto.com/ http://www.istockphoto.com/ http://www.dreamstime.com/ depositphotos.com.
