I'm looking for a way to change an image on a script I don't have access to (hosted on a 3rd party server).

The image I want to display is in a href but the img src shows a thumbnail version. 

I'm presuming I need some sort of jQuery script that replaces each instance (there could be more than one) with the appended version. 

The div is:

```
<div id="imagezoomcontainer">
<a target="_blank" class="chatlink" href="goodimage.jpg">
<span></span>
<img src="badimage.jpg" align="middle" border="0" height="100" width="100"></a>
</div>

```

I wish I just had access to the server - would save a lot of time!
