No image and no popup

I hava an ajax application that will not display an image, or create a popup from html stored in a file.

This is the code I am using for the popup:

echo '<script> 
function makewindows(){
child1 = window.open ("about:blank");
child1.document.write(' . json_encode($row2["ARTICLE_DESC"]) . ');
child1.document.close(); 
}
</script>';

      

        
        
        
      

    

And the resulting html

<script> 
function makewindows(){
child1 = window.open ("about:blank");
child1.document.write("<!-- +++++++++++++++++++++++++ Bitte \u00e4ndern Sie im eigenen Interesse nichts an diesem Code! ++++++++++++++++++++++++ -->\n<!-- +++++++++++++++++++++++++ Das kann massive Fehldarstellungen ihrer Auktion zur Folge haben! +++++++++++++++++++ -->\n<!-- +++++++++++++++++++++++++ ++++++++++++++++++++++++++ Ihr Supreme Team +++++++++++++++++++++++++++++++++++++++++ -->\n");
child1.document.close(); 
}
</script><br />

img src is a valid location and opens fine in the browser but does not appear on the page. I am getting a script error that does not contain any details.

edit: When only one file is called and not as part of the application, the resulting html file creates a link that creates a popup, but the source shows that nothing is assigned in the window:

child1.document.write("");

      

        
        
        
      

    

I made changes to the img src line:

<img src='".$lastImg."'>

      

        
        
        
      

    

As a result, html is returned:

<img src=''>
