PNG file saved using CURL is corrupt - php

Question

I'm using the following code from a SO thread, but the file that is outputted is a corrupt PNG file. I can't view it in any image editor. The image I'm trying to grab can be found at this direct link.
<?php
function getimg($url) {
$headers[] = 'Accept: image/gif, image/png, image/x-bitmap, image/jpeg, image/pjpeg';
$headers[] = 'Connection: Keep-Alive';
$headers[] = 'Content-type: application/x-www-form-urlencoded;charset=UTF-8';
$user_agent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.64 Safari/537.31';
$process = curl_init($url);
curl_setopt($process, CURLOPT_HTTPHEADER, $headers);
curl_setopt($process, CURLOPT_HEADER, 0);
curl_setopt($process, CURLOPT_USERAGENT, $user_agent);
curl_setopt($process, CURLOPT_TIMEOUT, 30);
curl_setopt($process, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($process, CURLOPT_FOLLOWLOCATION, 1);
$return = curl_exec($process);
curl_close($process);
return $return;
}
$imgurl = 'http://download.videos.framebase.io/5a94a14f-aca6-4fb0-abd3-f880966358ab/6bf94ebb-4712-4895-9c85-fb8d4a19d50c/8f8b778f-6335-4351-82e7-6f50fd7fdd06/1351620000000-000020/thumbs/00001.png';
if(file_exists($imgsave)){continue;}
$image = getimg($imgurl);
file_put_contents($imgsave,$image);
?>
What am I missing? Is it the headers I'm using? Is it the file? I tried saving the file just manually within my browser, and it loaded fine with my image editors.
any ideas would be much appreciated, thanks!

edit:
I know I marked this as solved, but on second thought, I still can't view the PNG's the server is saving. Here's what had been suggested so far:
<?php
function grab_image($url){
echo $url;
$ch = curl_init ($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);
$saveto = 'recent-image.png';
if(file_exists($saveto)){
unlink($saveto);
}
$fp = fopen($saveto,'x');
fwrite($fp, $raw);
fclose($fp);
}
grab_image("http://download.videos.framebase.io/2acd363b-ab1f-4305-8f1c-c1eaa6ebcc2a/abb6a3b7-414c-461b-a84c-56032060575d/e3682943-6959-456d-89db-8cd96647ddd4/1351620000000-000020/thumbs/00001.png");
?>
I've ran the script over and over again to no luck, once again, any help would be appreciated. Here's a sample of the PNG it outputs. thanks in advanced.

you can use normal function like
function grab_image($url,$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);
$saveto = "D:/test.png";
if(file_exists($saveto)){
unlink($saveto);
}
$fp = fopen($saveto,'x');
fwrite($fp, $raw);
fclose($fp);
}
grab_image('http://download.videos.framebase.io/5a94a14f-aca6-4fb0-abd3-f880966358ab/6bf94ebb-4712-4895-9c85-fb8d4a19d50c/8f8b778f-6335-4351-82e7-6f50fd7fdd06/1351620000000-000020/thumbs/00001.png','');
and make sure that in php.ini allow_url_fopen is enable..
