Reload

Question

I have an image at the URL http://192.168.1.53/html/cam.jpg (from a Raspberry Pi) and this image is changing very fast (it is from a camera).

So I want to have some Java

Answer 1

The problem is that the image src is not altered so the image is not reloaded.

You need to convince the browser that the image is new. A good trick is to append a timestamp to the url so that it is always considered new.

function update() {
    var source = 'http://192.168.1.53/html/cam.jpg',
        timestamp = (new Date()).getTime(),
        newUrl = source + '?_=' + timestamp;
    document.getElementById("img").src = newUrl;
    document.getElementById("img1").src =  newUrl;
    setTimeout(update, 1000);
}
