Find number of disabled images in a div.

Find number of disabled images in a div.

Hi, if I have a div that contains four images and I disable one how would I find the number of disabled images?

For example if I have:

  2. <div id="resutsBox">
  3.       <img src="gerrard.jpg" width="40" height="40" style="display:none" />
  4.       <img src="gerrard.jpg" width="40" height="40" />
  5.       <img src="gerrard.jpg" width="40" height="40" class="ui-disabled" />
  6.       <img src="gerrard.jpg" width="40" height="40" />
  7.       </div>
How can I find out that I have one image disabled?

Thanks.
