Answer 1

What I ended up doing was having the server map any request for an image at that directory to the source that I was trying to update. I then had my timer append a number onto the end of the name so the DOM would see it as a new image and load it.

E.g.

http://localhost/image.jpg
//and
http://localhost/image01.jpg

will request the same image generation code but it will look like different images to the browser.

var newImage = new Image();
newImage.src = "http://localhost/image.jpg";
var count = 0;
function updateImage()
{
    if(newImage.complete) {
        document.getElementById("theText").src = newImage.src;
        newImage = new Image();
        newImage.src = "http://localhost/image/id/image" + count++ + ".jpg";
    }
    setTimeout(updateImage, 1000);
}
