Using a form to insert an image using Javascript

Question

I'm using this javascript function to use a form to insert text into a set div.

I would like to be able to put an image url into a form and use this function to insert the url into an img tag instead of a div. What way could I achieve this?

Javascript:

function header01(){

    var head01v = document.getElementById('head01i').value;

    document.getElementById('head01c').innerHTML = head01v;
    document.getElementById('head01c').style.display = "block";

    return false;
}

I attempted to use the suggested solution, inputting the appropriate fields

 function image01(){

        var img = document.createElement('img');
        img.src = document.getElementById('imag01i').value;
        document.getElementById('imag01c').appendChild(img);

        return false;
    }

But to no avail, any additional help is greatly received.

var img = document.createElement('img'); img.src = theValueOfTheForm; Could that be of help? — 11684

Extending my comment to an answer:

It isn't that hard. First, check if you have a valid URL (more info on that here - first hit on Google), next, do this:

var img = document.createElement('img');
img.src = [the validated URL you obtained from the form];
document.getElementById('theElementYouWantToInsertTheImgIn').appendChild(img);
