Send an image through curl

Try to send the file via curl

$file = array('file' => "@".realpath('my.jpg').";type=image/jpeg"  ); 
$test = curlPOST($file, "http://site.ru/upload/", "http://site.ru", "c.txt" ,'', 60, 1);
echo $test;


function curlPOST($post_data, $url, $referrer='', $cookie_file='', $proxy='', $timeout=60, $header=0) {
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_USERAGENT, "Opera/9.10 (Windows NT 5.1; U; en)");
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
    curl_setopt($ch, CURLOPT_ENCODING,'gzip,deflate');
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: image/jpeg'));
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
    if($referrer) curl_setopt($ch, CURLOPT_REFERER, $referrer);
    if($header) curl_setopt($ch, CURLOPT_HEADER, 1);
    if($proxy) {curl_setopt($ch, CURLOPT_PROXY, $proxy);
            curl_setopt ($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);
            //curl_setopt($ch, CURLOPT_PROXYUSERPWD, "user:pass");
        //curl_setopt($ch, CURLOPT_PROXYAUTH, 1);
    }
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    if($cookie_file) {
        curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
        curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
    }
    $content=curl_exec($ch);
    curl_close($ch);
    return $content;
}

      

        
        
        
      

    

In response, we get a white screen if it is sent without :; type = image / jpeg. I am getting an error that the file cannot be downloaded. On-site loading happens via ajax. The image is also a valid cookie. What am I doing wrong?
