Read How to use with your plugin section.

Dear Takayuki, thanks for your reply, but I’m sorry, that section is for developers, I’m just a user with a couple knowledge in PHP/HTML that would like to add some code lines (copy/paste) into my modal code login. That sections doesn’t seem for me, to have any code to print the input field and image like <img> <input> and etc…

Still needing help in the code to place in the modal to show the input field, and the image to user enter the captcha.
Thanks and have a nice day.
