Though it seems odd, you can mix GET and POST like this:
<form class='form' action='zoom.php?img=<?php echo intval($_GET['img']);?>' method='post'> <b>".$user_name_s." …

There are a couple of ways of implementing this. The usual way (from my point of view) is:
On the beginning you check for existence of $_POST['submit'], which signals that the form was submitted. Then you check if image description exists and is valid. You sanitize/escape it and send it to the database. Then you can either display the same page or redirect to other page (i.e back).
if(isset($_POST['submit'])) {
if(isset($_POST['image_des']) and !empty(isset($_POST['image_des'])) {
// escape the description text and insert it into database
// ...
}
}
The more complex way is using Ajax but it is a question whether you need this.
