php and html image tag...

Ok here is my problem, I have a piece of code that queries the database pulls the results of a table into an array, on another file the results of that array are used with a require function and then each variable is echoed to the screen where I need it, I have a piece of javascript to open a pop up window and the code is as such... <a href='javascript:openPopWin("<?php echo $ad01; ?>", 420,545, "", 0, 0)'onmouseover="window.status='This weeks full page ad';return true"> As you can see I have placed the results of the array within my <a href=" tag and it works fine.. however the second part <img src="<?php echo $ad01_t; ?>" width="200" height="100" vspace="0" hspace="0" border="0"></a> Will not pull the results of the array into the page, I don't know if this is a valid piece or not, any help would be great. Thanks in advance. Jas
