First find a picture you like and when you click on it, it will open up in a new window. When you click other pictures they will open in that same window. Once the picture has downloaded, right mouse button click on it to save it or print it out. The number follwing the picture description is the size of the file. K is kilobytes and 21K is 21,000 bytes, but don't worry the pictures are all pretty small.
To make up for my lack of Alvin pictures here is a link to some Alvin and the Chipmunks colouring pictures. They are the old school pics from the original cartoon series from 1969.
