Hi Cindy , I make my scr images jpg 5 or sometime 4 and they look ok, but just experiment and see what looks good. When I make my images in photoshop I resize them to 1024x768, you could choose 800x600, but I think most people are on the former nowadays. The I use image ready to optimise them, as if for a web site, then save at jpg quality 4 or 5. For shows that will be projected I always save at best quality jpg, in photoshop that's jpg12. Hope that helps. Alan
