How can I create new attribute based on img src and use original src value for another?
<p>I want to use Lazy Load which requires an attribute named "data-original" which points to the original image src value.  I can create the new "data-original" with the value from the src attr like this without a problem:</p>

<pre><code>  $('img.lazy').each(function() {
    a =  $(this).attr("src");
        $(this).attr("data-original", a);
   }); 
</code></pre>

<p>But, if I follow with this (which Lazy Load needs the src value to be):</p>

<pre><code>  $('img.lazy').each(function() {
    b =  "img/grey.gif";
        $(this).attr("src", b);
   }); 
</code></pre>

<p>The data-original and src atrr both become "img/grey.gif"</p>

<p>Thanks from the newbie!</p>
