image source from PHP

Hello, I want to make a sit where an image comes from a database. In the db I store only the filename and path. I have the following code: <?php $ps = '"Pic/'.$row_photos['Photo_File_Name'].'"'; echo $ps;?> <img src=<?php $ps; ?> > The echo line print the good string e.g.: "Pic/Myphoto.jpeg" But I can't see the image. Only a one small whit box wit red x (no image). And if I try to put with hard code: <img src "Pic/Myphoto.jpeg" > It works fine. What can I do? Thanks!
