Answer 1

It works if you remove the options to POST and do a regular GET request:
<?php
function imagedownload($url, $saveto)
{
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$result = parse_url($url);
curl_setopt($ch, CURLOPT_REFERER, $result['scheme'] . '://' . $result['host']);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0');
$raw = curl_exec($ch);
curl_close($ch);
if (file_exists($saveto)) {
unlink($saveto);
}
$fp = fopen($saveto, 'x');
fwrite($fp, $raw);
fclose($fp);
}
$url = "http://scontent-frt3-1.xx.fbcdn.net/v/t1.0-0/cp0/e15/q65/p320x320/13700038_850487491753797_6227258625184891703_n.jpg?oh=793ecde8db1a8e65789534907d08b25e&oe=57F1DDFF";
$konum = "test.jpg";
$yolla = imagedownload($url, $konum);

I had try in my localhost this code and it working well.
<?php
ini_set('display_errors', 1);
function imagedownload($url,$saveto){
$ch = curl_init ($url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
$raw=curl_exec($ch);
curl_close ($ch);
if(file_exists($saveto)){
unlink($saveto);
}
$fp = fopen($saveto,'x');
fwrite($fp, $raw);
fclose($fp);
}
$url="http://scontent-frt3-1.xx.fbcdn.net/v/t1.0-0/cp0/e15/q65/p320x320/13700038_850487491753797_6227258625184891703_n.jpg?oh=793ecde8db1a8e65789534907d08b25e&oe=57F1DDFF";
$konum="/var/www/html/jsPDF-master/examples/test.jpg";
$yolla=imagedownload($url,$konum);
?>
And result
And one note: Please make sure the directory for save image must have write permission.
Example: chmod -R 777 /var/www/html/jsPDF-master/examples
Or ensure that in php.ini allow_url_fopen is enable
