Licensing fees for Getty Images are typically expensive, but now you can embed pictures from Getty for free on your website. The images carry no watermark, there are no view limits and you are free to use any number of images. It works something like YouTube, in that you can embed an image from their site using just a line of code. In the future the images may carry advertising, but for now they don’t, so enjoy!
