I am trying to clone an image which is generated randomly. Although I am using the exact same url a different image is load. (tested in chrome and firefox)
I can't change the image server so I am looking for a pure javascript/jQuery solution.
How do you force the browser to reuse the first image?
Firefox:

Chrome:

Try it yourself (maybe you have to reload it several times to see it)
Code: http://jsfiddle.net/TRUbK/
$("<img/>").attr('src', img_src)
$("<div/>").css('background', background)
$("#source").clone()
