Personally, I find them a bit expensive for simple blogging or non-commercial presentations, but they are undeniably a great resource. Readers had some good suggestions for alternatives to Shutterstock, however, such as searching Flickr’s Creative Commons and either asking the photographer for permission or simply giving a link attributing the artist. Another great and creative idea is to create your own library of stock photos. Start snapping shots of signs, (“Stop,” “Exit” “No Exit,” etc.) and be your own Shutterstock. Beats paying fees and is far more creative, and fun.
