Are you trying to gather pictures for a slideshow to show your students' parents at Back to School Night? I know a lot of my teachers have been busy taking tons of pictures. We have been using Animoto (you do have to sign up for the free 6 month education account trial) and Slidely. I REALLY like Slidely because it is FREE and easy to use. Here is one I put together with some AMAZING Virginia Bloggers' blog buttons. You have to check out their blogs!
