How to load image into bootstrap modal with javascript

My setup is 4 links (below). I want each link to open myModal, but
depending on which link gets clicked, a different image file should load
in the modal. I got it working for one of the links.
<li><a href="#myModal" data-toggle="modal">6 Teams</a></li>
<li><a href="#">5 Teams</a></li>
<li><a href="#">4 Teams</a></li>
<li><a href="#">3 Teams</a></li>
<!-- Modal -->
<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog"
aria-labelledby="myModalLabel" aria-hidden="true" style="width:800px;">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"
aria-hidden="true">×</button>
</div>
<div class="modal-body">
<img src="/images/brackets/6teamDouble1.jpg">
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
</div>
</div>
How do I get this to work for each link without building a separate modal
for each one?
