ABC Scavenger Hunt

I feel like the Picasa Slideshow/ Scavenger hunt was a great activity to incorporate in my classroom. I didn't like that I had to edit each picture before I put it back into the slideshow. I would prefer a tool that allows me to edit as I create the slideshow. Right now I can't think of any other particular uses for Picasa; however, I am open to any fun or creative ideas!
