To answer your question, we need to get some background information upfront...
1. SQL table structure :
Do you have a specific field in your table that DataAssist calls that is "reserved" specifically for an image filename?
2. The actual images directory :
Will that ever change?
In order to move forward here, I'm going to assume the following..
1. Yes you have a specific field reserved for an image filename.
2. The images directory is permanent and unique.
The following should come as some help...
<img src="images/<?php echo $row_WADARecordset1['image_fieldname']; ?>" width="1024" height="768" border="0">
In the above code, I'm using a standard HTML tag for an image and then combining the static images directory along with a dynamic PHP call to the DataAssist image filename binding, then I'm identifying the width and height and no border.
The Recordset and image_fieldname should match whatever they actually are in your configuration.
