jquery addclass if image has specific alt tag
<p>I have some images, all of which have alt tags.</p>

<p>I am trying to add a class to all of the images which have a certain alt tag.</p>

<p>So to put it in plain terms:</p>

<p>If image <code>alt</code> tag = "dog" then add class "canine"</p>

<p>Any ideas?</p>

<p>thanks</p>
