You can use the setTimeout method from javascript, and after every few seconds change the background image in the body.

document.body.background = "image.gif"

eg.

setTimeout('changeImage(1)',1000);

function changeImage(i) { if i == 4 return;

document.body.background = 'image'+i+'.gif'; setTimeout('changeImage('+(i+1)+')',1000); }

You should have the images image1.gif, image2.gif and so on in the same folder as your gadget.html
