the directory was simple-captcha and not simple_captcha
since then i renamed it to simple_captcha and activated the plugin it has started to work..
this simple problem would have been solved if the original filename was itself named correctly.
i request the author to again zip the files to simple_captcha.1.2.zip to avoid hassles for other users.

recaptcha is jus too much and sometimes is slow ..i just want a simple captcha..already tried ‘cryptograph- images not readable’ and ‘simple captcha – does not work’
