<SCRIPT language=JavaScript1.2> <!-- function boom(n) { if (window.top.moveBy) { for (i = 10; i > 0; i--) { for (j = n; j > 0; j--) { window.top.moveBy(0,i); window.top.moveBy(i,0); window.top.moveBy(0,-i); window.top.moveBy(-i,0); } } } } function callJS(jsStr) { return eval(jsStr) } --> </SCRIPT> <A href="#" onmouseover="javascript:callJS('boom(3)');"><IMG border=0 src="images/3.gif" ></A>
