Is the variable $row specified?
Plus can you specify $page_name as a field?
I would have thought it was something more like this:
mysql_select_db('a0017855');
$query ="select * from Eli2where page_name = "\etruria\" ";
$result=mysql_query($query)
or die ("Couldn't Execute Query");
while ($row = mysql_fetch_array($result))
{ echo $row["bckgrnd_image"]; }
