this is a little confusing.
in the first post, you report that you are using the following code for the image:
<img src="../images/art/thm/<?php echo $row_WADAitems['ItemImage']; ?>" alt="" id="WADAPageHeaderImage" />
then you report the source code generated on the page as:
<img src="images/art/CelticMandala.jpg" alt="" id="WADAPageHeaderImage">
there is no way the php code could generate that source code. the path i nthe php code:
is not the same as the path in the browser source code:
the php code is correct, but it is not the code being run on the server to generate the image path.
I would question whether the version of the page on the server is the same as the one on your local system.
