Count images with jquery from another page

Is it possible to use this jquery to count images from another page

but this one doesn't work, any ideas?

Code:

$(function(){
$("<img />").load("/f11-test .main",function(){
var x=$(this) .attr('src', 'http://www.servimg.com/u/f22/15/62/63/03/no_new12.png') .length;
if{}
else{}
}
});
});
