Thanks Jason. All working fine now. I just had to change
<img src="images/<?php echo $row_RecordsetName['fileName']; ?>" />
<img src="../Powergallery/images/<?php echo $row_rsRandomImage['fileName']; ?>" />
as my images folder is in a folder called "Powergallery" & obviously my recordset is called "rsRandomImage"
I appreciate your help.
