I am in the process of completing a photoShow. In making the show, I moved some photos to their correct sequence; in some cases I "copied" and then "pasted" the photos in the correct positions. The original photo changed to an icon of a camera, which I cannot delete. When the show gets to these icons, I get a message that an error has occurred and PhotoSHow must shut down. Has anyone come across this problem? How can I delete these camera icon thumnails?
