Earlier I wrote about Flipsnack as a way to present flippable books and magazines. In fact there is a whole family of "Snack Apps" to choose from. I tried Photosnack today and was very happy with the easy of use, and the ability to sign in using Google or Facebook rather than having to create a new account. It is a Freemium service, so to get all the features, you have to pay a little more. But it is a simple way to add a slick slide show to your blog or webpage.
