javascript error when trying to use getElementById: 'null' is null or not an object?

Asked by ohmErnie in JavaScript, Programming for ASP.NET

I thought this was pretty simple. I have an ASP:Image named img_load. I have a javascript set up to run onclick. All I want to do is set the visibility to true. Simple right? But I'm getting a 'null' is null or not an object error when trying to do anything with my javascript object.  The image is in an update panel. Does that make a difference? Is that what's causing my error?Start Free Trial

            var img;
            img = document.getElementById("img_load");
            img.visible = true;   
        }
    </script>
