I have this code a friend made, and it is javascript, but I don't see any commands that I saw when going through the tutorial.

java script: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.getElementsByTagName("img"); 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)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval('A()',5); void(0)

try laying the script out more simple:

java script: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.getElementsByTagName("img");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)+"px";  DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"; } R++}setInterval('A()',5); void(0);

it uses HTML DOM .. so that's probably why you don't see many of the commands you learnt.i'm guessing with it starting with "java script:" it's being stored in the element (eg. ....onclick="java script:R=0.....") so you will have to keep it as you have it now.

Yeah, most of the time when you are using javascript to do various things with a webpage, you are actually using the HTML DOM. I'd guess that about 70% of client-side scripting (if not more) is HTML DOM rather than javascript. Go through the tutorial here: http://www.w3schools.com/htmldom/default.asp
