Receiving captcha information for validation.
Captcha validation has been adjusted.
The dimensions for both the 'image_head' and 'image_body' captcha images have been increased to provide a clearer and more readable captcha for users. 'Image_head' has been updated from 150x40 to 500x75, and 'image_body' from 300x240 to 500x500.
Now a new captcha is created to check for a bot.
