find if a img have alt in jquery if not then add from array
<p>first need to find all img in the sites</p>

<pre><code>$("#body").find(img)
</code></pre>

<p>and then check if the img have the "alt" attribute, if image have the attribute it'll be escaped and if it not have one or the alt is empty,a string will be randomly added to img from a list or array.</p>

<p>I now that i have to use .each() some how in a function but I'm new to jquery so a little bit help would be perfect.</p>
