the code you have for displaying the image:
<img src="/home5/paducahi/images/<?php echo $row_WADAproducts['ProductThumb']; ?>" alt="Image Name" border="0" class="WADAResultThumb" />
looks correct.
what does it show in the browser source for the image path? are you sure the ProductThumb column is returning an image name? and that the path is correct?
Do you have a link where i could see this?
