How to use reCAPTCHA as pop up window instead of part of the web?
<p>I made a webpage which can provide some direct downloads. Therefore I only want real human, not crawler, to download my files. I tried to use Google reCAPTCHA but it is part of the webpage - visitors can still use the download links and doesn't have to worry about the reCAPTCHA at all. Is there a way to mandate visitors to pass the verification first? For example, is it possible to pop up reCAPTCHA before the whole page is loaded? If that's doable, how can I do it? Thanks!</p>
