†Firefox 5+, Internet Explorer 9+, and Opera 11.50+ will fall back to a normal image without a hidden referrer.

Getting Started

1. Download hotlink.js (unminified).
2. Replace <img src="..."> with <img data-src="..."> for every image that you want to hotlink on your site.
3. Include <script type="application/ecmascript" async="" src="hotlink.js"></script> right before </body>.

API

void hotlink(HTMLImageElement image)

If you are using dynamically inserted images, you'll want to use the API to hotlink them.

Example

var image = new Image(300, 100);
image.setAttribute("data-src", "http://example.com/image.png");
document.documentElement.appendChild(image);
hotlink(image);
