jeez, stop complaining people, heres the thing you have to paste in the address bar
(i think this is the one posted, i didnt try it but i assumed it was this one, its been popping up all over the place latly)
Code:
javascript:R=0;x1=.1;y1=.05;x2=.25;y2=.24;x3=1.6;y3=.24;x4=300;y4=200;x5=300;y5=200;DI=document.images;DIL=DI.length;function A(){for(i=0;i<DIL;i++){DIS=DI[i].style;DIS.position='absolute';DIS.left=Math.sin(R*x1+i*x2+x3)*x4+x5;DIS.top=Math.cos(R*y1+i*y2+y3)*y4+y5}R++}setInterval('A()',5);void(0)
If it dosnt work then one of two things went wrong
1. Your computer sucks and you need to upgrade from windows 3.1
2. You did it wrong
More likley to be 2 to be honest
For the higest chance of success just paste it in the address bar of this page (not a new tab/new window) hit enter and scroll to the top of the page
EDIT: works better if you go to google images, search for something and then do it.
