This number is then stored in a session and then in the form you must enter the number into the field that is on the image. But obviously bots are unable to view the numbers on the image so they cant complete the form and once the form has been submitted we check if the number matches and if it doesn't match then that means its a bot etc. What is happening is there is a image generated with a random number.
