If you are using Windows ME then all you have to do is store your photos in 'My Pictures' and then select your screen saver in the display properties as 'My Pictures Screen Saver'
They will then run as your screen saver automatically.
Otherwise-
"This handy program allows you to create your own screen saver using your own favorite photos, internet images (gif, jpg, bmp, jif, dib), and words of wisdom. Over 40 customizing features and 9 transition effects. Resize your image to fit the screen. No Programming Required!"
