Live demo on https://http2pic.haschek.at/

Dependencies

• wkhtmltox
• curl extension for PHP apt-get install php5-curl
• Make sure the server has the "timeout" command apt-get install coreutils

Install

• Download this repo and extract it somewhere on your webserver

With WKHTMLToImage

• Install wkhtmltox on your server
• Make /usr/sbin/wkhtmltoimage executable for the user that runs the webserver. For Apache it's the www-data user. Or use sudo

With PhantomJS

• Install PhantomJS. eg via npm install -g phantomjs
• Make /usr/bin/phantomjs executable for the user that runs the webserver. For Apache it's the www-data user. Or use sudo

Upgrade

Whenever you come to this page you can just download the repo again and overwrite the existing files. Should work out of the box

Usage

After you extracted the contents of this repo to your webserver and can access the page and it will tell you how to use the API.

But it's as simple as:

https://your-url-and.path/api.php?[OPTIONS]&url=[WEBSITE_URL]

The requested page will render as image (not provide a link). So you can use the path to your api.php file like so:

<img src="https://your-url-and.path/api.php?url=http://xkcd.com" title="screenshot of xkcd.com" />

Example php script to proxy an image to the local server

<?php
    $targeturl = 'http://www.xkcd.com';
    $url = 'https://http2pic.haschek.at/api.php?url='.rawurlencode($targeturl);

    $ch = curl_init($url);
    $fp = fopen('xkcd.jpg', 'wb');
    curl_setopt($ch, CURLOPT_FILE, $fp);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_exec($ch);
    curl_close($ch);
    fclose($fp);
?>
