This is the original code from my tutorial on how to use the Imgur API with Tweetbot for Mac. Imgur has since iterated their API, which requires a new script. I'm just archiving the old one here, while I update the post for version 3. http://www.webmaster-source.com/2012/10/20/adding-imgur-support-to-tweetbot-for-mac/

<?php
 
class TweetbotImgurEndpoint {
 
 
    private $api_key;
    private $api_url = "http://api.imgur.com/2/upload.json";
    private $file_temp_location;
    private $file_name;
     
 
 
    function __construct($api_key, $file_temp_location, $file_name) {
        $this->api_key = $api_key;
        $this->file_temp_location = $file_temp_location;
        $this->file_name = $file_name;
        $this->upload();
    }
 
 
 
    private function upload() {
 
        $image_info = getimagesize($this->file_temp_location);
 
        if ($image_info !== false && in_array($image_info['mime'], array("image/png", "image/jpeg", "image/pjpeg", "image/gif"))) {
            $fh = fopen($this->file_temp_location, "rb");
            $file_contents = fread($fh, filesize($this->file_temp_location));
            fclose($fh);
