That is a really good idea with taking my own pictures as well. Check out the timeslips.org website they have sample stories. I was looking through my notes from a class and got these websites for great pictures as well, oddanimals.com; skoopy.com; and picturepop.com. The sky is the limit with this activity... depending on the person leading it can go in a lot of directions. People suggest writing down word for word everything that is said. Then you can write up the story with the photos... and who knows eventually put them into a book.
