Al, This slideshow contains 231 pictures. I do not bairgain on the picture quality and size as long as the whole P2E show fits on a CD. I know that the resolution is way over what is required for a decent screen presentation, but most PC handle the resizing without any problem and in fact it saves me the time to do the picture resizing after all pictures are finetuned (framing, sharpening, color cast, perspective correction ...) More, I keep the original high quality pictures for other use like printing ... Concerning music addition : I always use the MP3 music file format. In this paticular show, I added no music. Peter.
