Why are you putting images inside of a table? table = tabular... you only use table tags for data... never images. You can recover some cart speed by using this trick.
instead of table tags use div tags and limit your image by adding style comment to your image i.e. style="float:left"
example:
<div style="whatever-you-want;">
<img src"./images/D/xxxxxxxx.jpg" style="width:70px; height:70px; float:left; what-ever-else-you-want;" />
</div>
Just use similar code to this around the smarty tags and you'll start to sort out how to control your images a lot better.
