TEMA:

Dear Mario,
I found this topic really useful and I'm changing the code to let the Captcha be easier and more readable.

Is there a way to define how many chars will be generated in the image and to let only numbers appear?

Kindest regards

Hello,

You wrote "Is there a way to define how many chars will be generated in the image and to let only numbers appear?".
Unfortunately, there is no way to do so.
What can be changed is what is listed in the secureimage_show.php file, which is text transparency, number of lines over the text, color and whether the existing words will be used or no.

Regards,

Mihaela
