How Can I Upload Photos to Instagram Without Using the Official API?

Reverse Engineering Instagram's API: A Deep Dive into Photo Uploads

Despite the absence of an official API function for posting pictures, a workaround is possible by reverse engineering Instagram's API. By utilizing the provided code snippet, you can achieve image uploads directly from PHP.

function SendRequest($url, $post, $post_data, $user_agent, $cookies) {
    // Set cURL options for API requests
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://i.instagram.com/api/v1/'.$url);
    curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

    // Handle post requests
    if($post) {
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
    }

    // Cookie handling
    if($cookies) {
        curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies.txt');            
    } else {
        curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies.txt');
    }

    $response = curl_exec($ch);
    $http = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);

   return array($http, $response);
}

    // Generate a random GUID
    return sprintf('%04x%04x-%04x-%04x-%04x-%04x%04x%04x',

     // Generate an API signature
