Basically it is saying there are three images and it wants to cycle through
them. Therefore when the page is first sent to the browser:
image1 = 'thau.gif'
image2 = 'sky.gif'
image3 = 'monkey.gif'

When you click, then:
image1 = 'sky.gif'
image2 = 'monkey.gif'
image3 = 'thau.gif'
'sky.gif' is then swapped onto the page

On the second click:
When you click, then:
image1 = 'monkey.gif'
image2 = 'thau.gif'
image3 = 'sky.gif'
'monkey.gif' is then swapped onto the page

etc..etc..etc..

I didn't take a detailed look at the code, but that's what it appears to be
doing to me :)
