javascript/jquery: get info for a remote image
<p>I have an image that has "src" pointing to an external server, like this:</p>

<pre><code>   &lt;img src="http://somewhere.com/script.php?id=1234"&gt;
</code></pre>

<p>The image returned is .png and it can be returned as a "X" image or "O" image.</p>

<p>How can I determinate if the image is X or O with javascript/jquery? Calculating md5 of the loaded image? In case how can I access to the image bytes and calculate md5?</p>
