All depends on what the end product is; a slide show on a laptop or projected 20 feet wide in a theatre. For best performance, images should be created to match the document size in; Inspector > Document > Slide size.
The slide size should as a minimum match the screen resolution of the Mac in;
system preferences > displays. The higher the number of pixels the better the quality.
However, many images are supplied that are much smaller than are required, resulting in them being enlaged beyond there best.
