What is wrong with this syntax - code snippet

[Mal1]

I'm getting a syntax error on line 109 with this code on Dreamweaver (not my code), the code seems to work but would like to fix the syntax if possible.

<?php foreach ($gallery->images as $image_id): ?>
                        preloaded<?php echo $image_id; ?> = new Image(); 
                        preloaded<?php echo $image_id; ?>.src = "img/<?php echo $rug->data['id']; ?>_<?php echo $image_id; ?>_medium.jpg";
                     <?php endforeach; ?>

if "preloaded" is a variable you need $ prefix

He's trying to generate js.

 

There's absolutely no reason to keep starting and stopping PHP tho.
