Captcha image not shown in my website

Hi all,I've started recently creating a website for a family event. I want to include a reCaptcha in a form to avoid spam. I'm using the PHP plugin and have followed these instructions: https://developers.google.com/recaptcha/docs/php?hl=es.I'm testing the captcha in the local host using global keys (they are supposed to work in the local host) but I can't manage to get the captcha image to be shown (I've tried in Firefox and in Eclipse internal browser).I've attached the files so you can check if I'm making any mistakes. In the attached files I've substituted my keys by private_key and public_key but I've made the tests with the right keys which appear in my reCaptcha account.I've read in the recent posts that some user are experiencing problems with reCaptcha and actually I've realized that some of them have moved reCaptacha from their websites. Is reCaptcha experiencing any known issue?Thank you in advance! -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
