What's the image id? If it's a string you need to wrap it in quotes, but other than that it's fine. I just ran it and got no errors, so there must be something else causing the problem. — Reinstate Monica Cellio

Are you using href attribute of this input element? If not then you don't need that. Also I would suggest you to attach the click handler using jQuery. But if your markup and server side code does not help then you can try this.

<script type="text/javascript">
            function popup(image_id){
                $.ajax({
                    cache: false,
                    type: 'POST',
                    url: 'popup.php',
                    data: 'image_id=' + encodeURIComponent(image_id),
                    success: function(data) { 
                        }
                });
                return false;
            }
</script>

<input href="#dialog" type='button' value='Open' onclick="return popup('<?php echo $image['image_id']; ?>');" />

You must be having js error on the page because of which popup function is not parsed by JS engine. Take a look in the console if you see any errors.
