There are "@" issue on multipart POST requests.

Solution for PHP 5.5 or later:
- Enable CURLOPT_SAFE_UPLOAD.
- Use CURLFile instead of "@".

Solution for PHP 5.4 or earlier:
- Build up multipart content body by youself.
- Change "Content-Type" header by yourself.

The following snippet will help you :D

<?php

/**
* For safe multipart POST request for PHP5.3 ~ PHP 5.4.
*
* @param resource $ch cURL resource
* @param array $assoc "name => value"
* @param array $files "name => path"
* @return bool
*/
function curl_custom_postfields($ch, array $assoc = array(), array $files = array()) {
   
   
// invalid characters for "name" and "filename"
   
static $disallow = array("\0", "\"", "\r", "\n");
   
   
// build normal parameters
   
foreach ($assoc as $k => $v) {
       
$k = str_replace($disallow, "_", $k);
       
$body[] = implode("\r\n", array(
           
"Content-Disposition: form-data; name=\"{$k}\"",
           
"",
           
filter_var($v),
        ));
    }
   
   
// build file parameters
   
foreach ($files as $k => $v) {
        switch (
true) {
            case
false === $v = realpath(filter_var($v)):
            case !
is_file($v):
            case !
is_readable($v):
                continue;
// or return false, throw new InvalidArgumentException
       
}
       
$data = file_get_contents($v);
       
$v = call_user_func("end", explode(DIRECTORY_SEPARATOR, $v));
       
$k = str_replace($disallow, "_", $k);
       
$v = str_replace($disallow, "_", $v);
       
$body[] = implode("\r\n", array(
           
"Content-Disposition: form-data; name=\"{$k}\"; filename=\"{$v}\"",
           
"Content-Type: application/octet-stream",
           
"",
           
$data,
        ));
    }
   
   
// generate safe boundary
   
do {
       
$boundary = "---------------------" . md5(mt_rand() . microtime());
    } while (
preg_grep("/{$boundary}/", $body));
   
   
// add boundary for each parameters
   
array_walk($body, function (&$part) use ($boundary) {
       
$part = "--{$boundary}\r\n{$part}";
    });
   
   
// add final boundary
   
$body[] = "--{$boundary}--";
   
$body[] = "";
   
   
// set options
   
return @curl_setopt_array($ch, array(
       
CURLOPT_POST       => true,
       
CURLOPT_POSTFIELDS => implode("\r\n", $body),
       
CURLOPT_HTTPHEADER => array(
           
"Expect: 100-continue",
           
"Content-Type: multipart/form-data; boundary={$boundary}", // change Content-Type
       
),
    ));
}

// Create a CURLFile object
$cfile = curl_file_create('cats.jpg','image/jpeg','test_name');

// Assign POST data
$data = array('test_file' => $cfile);
curl_setopt($ch, CURLOPT_POST,1);

i've seen some downvotes , here is a small example of using curl to upload image .

<?php
$target
="http://youraddress.tld/example/upload.php";

# http://php.net/manual/en/curlfile.construct.php

// Create a CURLFile object / procedural method
$cfile = curl_file_create('resource/test.png','image/png','testpic'); // try adding

// Create a CURLFile object / oop method
#$cfile = new CURLFile('resource/test.png','image/png','testpic'); // uncomment and use if the upper procedural method is not working.

// Assign POST data
$imgdata = array('myimage' => $cfile);

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $target);
curl_setopt($curl, CURLOPT_USERAGENT,'Opera/9.80 (Windows NT 6.2; Win64; x64) Presto/2.12.388 Version/12.15');
curl_setopt($curl, CURLOPT_HTTPHEADER,array('User-Agent: Opera/9.80 (Windows NT 6.2; Win64; x64) Presto/2.12.388 Version/12.15','Referer: http://someaddress.tld','Content-Type: multipart/form-data'));
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // stop verifying certificate
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true); // enable posting
curl_setopt($curl, CURLOPT_POSTFIELDS, $imgdata); // post images
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true); // if any redirection after upload
$r = curl_exec($curl);
curl_close($curl);

?>

Usage Example :

curl_setopt($curl_handle, CURLOPT_POST, 1);
$args['file'] = new CurlFile('filename.png', 'image/png', 'filename.png');
curl_setopt($curl_handle, CURLOPT_POSTFIELDS, $args);
