jQuery overall element index

Is there a way to use jQuery index() method to find the index of an element related to the overall document?

I mean, if I have a bunch of img tags in a document, is there a way to know, regardless of their position in the document, their index?

example :

<body>
<img />
<div>
   <img />
   <div>
      <img />
   </div>
</div>
</body>

I've tried using $(window), $(body), $(document), but they all fail. I really n开发者_StackOverfloweed the overall index of the element.

Cheers!

index() returns the position in a given collection:

$('img').index('id');

Do you mean

$('img').index(imgElement);

$('*').index(imgElement);

$('*').index($('.someClass'))
