2 errors fixes described below. ---- Now that's an ultra light CAPTCHA. Thanks. ---- 1) Have broken image in <img /> and error msg on captcha.php: ... "Malformed header from CGI script: libpng warning: iCCP: known incorrect sRGB profile" ... Fix ... : Assign sRGB to all background PNGs in graphics editor like GIMP. This also reduces size of those images to like 40%. ---- 2) On Ubuntu apache2 I had no characters generated ... Fix ...: change fonts paths from 'font.ttf' to './font.ttf', so add './' part before the actual path.
Provides no instructions. readme.txt is only used for self promotion. 2 thumbs down.
