Ok
Have changed the hidden value and button names:
<form action="" method="post">
<input name="DeleteImage1" type="hidden" value="<?php echo $row_WADAwebsites['Image1']; ?>" />
<input name="DeleteButton1" type="submit" value="Delete Image" /></form>
and the lookup record have set to both
<?php echo ((isset($_POST[""]))?$_POST[""]:""); ?>
and
<?php echo((isset($_POST["DeleteImage1"]))?$_POST["DeleteImage1"]:"") ?>
but neither way is working... :(
