The image generator was designed so that the code displayed on the picture cannot in practice be interpreted by a machine. This involves several random-based steps that sometimes (rarely) result in the code being difficult to read. If this happens to you, simply download the image again by clicking on the “save the image file” link, and you will get another image displaying the same code. It would also be most helpful if you could of the image.
We are constantly improving the quality of the challenge system, and we would appreciate your assistance to test our next technology. It should need less than 10 seconds of your time.
