jQuery Image manipulation

[eluser]Fireclave[/eluser]
the image will rotated, the request is okay too, but the rotated image will not be updated.

// When Image ist rotated, then show the same picture again (reload)
$('#grafik').attr('src', '<?php echo base_url().'bilder/' ?>'+data);

This should update the picture or not ? i load the same image like before.
