./classes/Image.php:

<?php
class Image {

        public static function uploadImage($formname, $query, $params) {
                $image = base64_encode(file_get_contents($_FILES[$formname]['tmp_name']));

                $options = array('http'=>array(
                        'method'=>"POST",
                        'header'=>"Authorization: Bearer a5d4b7d7eb41f3c2049e1212c628996839cc3066\n".
                        "Content-Type: application/x-www-form-urlencoded",
                        'content'=>$image
                ));

                $context = stream_context_create($options);

                $imgurURL = "https://api.imgur.com/3/image";

                if ($_FILES[$formname]['size'] > 10240000) {
                        die('Image too big, must be 10MB or less!');
                }

                $response = file_get_contents($imgurURL, false, $context);
                $response = json_decode($response);

                $preparams = array($formname=>$response->data->link);

                $params = $preparams + $params;

                DB::query($query, $params);

        }

}
?>

this is the php page given to the user so he can upload his profile picture to the database.

if (Login::isLoggedIn()) {
        $userid = Login::isLoggedIn();
} else {
        die('Not logged in!');
}

if (isset($_POST['uploadprofileimg'])) {

        Image::uploadImage('profileimg', "UPDATE users SET profileimg = :profileimg WHERE id=:userid", array(':userid'=>$userid));
        Image();
}
?>
