You need to display a captcha image in your HTML forms, so LaraCaptcha provides a image url like what you see below that you can use easily.

To do this, open resources/lang/en/validation.php and add following item to the existent array.
Of course you are able to use :attribute in the validation message instead.
This approach enables you to use Laravel internationalization tools.
