My friend, Jo Linsdell, created a promotional video for her books using animoto.com. I didn't find it all that easy to figure out, but my technology skills can be a bit lacking at times. I was able to add images without an issue and add a title, but I couldn't get a text box to appear later in the video or at the end. Unlike Windows Movie Maker, it doesn't seem like you can easily switch images between windows either.
You can set up a free account and create a short 30 second video. If you would like more options and longer videoes, you need to pay for them. Let me know what you think.
