I created a slideshow presentation with music in Adobe Photoshop. While I was working on it some of the slides showed up blank as I was adding music. Somehow I brought the missing pics back in and thought I was all set. A few hours later I went to watch it again and every photo was blank. The only things left in my project were the slides I had framed with color and the text I had written introducing each section. I also lost all the pics in the album I had been working on and the tagged folder of the same person in the organizer. The pictures I used in the project are still in "My Pictures" but I am afraid to go to all that work all over again just to have the same thing happen. Any ideas as to what happened?
