I am using Grégoire's PHP Captcha library, on local host, it is working fine, as of creating images, and sending to browser. But when same code is on remote server, Captcha Image is not being displayed client side. Since in both cases each image request is responded with around 20kB of data, I am sure the image is being downloaded. And from the looks of it, it seems a valid base64 of an image. the only difference I have noticed is that when logging the base64 string, it is usually shorter, around 8kB, while the base64 from localhost is just as much as the real image, ~20kB. But with my knowledge, I don't know how to use this information. Any Guidelines?
snippet of code:
$captcha = new Gregwar\Captcha\CaptchaBuilder; $captcha->build( Config::get('CAPTCHA_WIDTH'), Config::get('CAPTCHA_HEIGHT') ); header('Content-type: image/jpeg'); $captcha->output();
I have used wamp on my windows 7, but installed apache2, php5 separately on remote ubuntu 14.04.
Localhost: apache 2.4.9 , php 5.5.12
Remote Server: apache 2.4.7 , php 5.5.9
In both cases No error is being generated whatsoever.
a working base64 from localhost:
data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD//gA7Q1JFQVRPU ... iiigAooooAKKKKACiiigD//2Q==
which is usually around 20 kbytes long.
a not-working base64 from remote server:
data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAYABgAAD//gA7Q1JFQVRPU ... I0vQ7A
which is usually around 8 kbytes long.
