Image corrupted after php curl transfer FTP - php

Question

I am using the following code to transfer an image and it is working except the jpg is corrupted after the transfer. Is says invalid image format and shows a blurred image.
I tried using regular php without curl and get the same results.
Does anyone know why whatever I try works but corrupts the image.jpg
$curl = curl_init();
$fh = fopen("test.jpg", 'w');
curl_setopt($curl, CURLOPT_URL, "ftp://{$serverInfo['user']}: {$servererInfo['password']}#{$serverInfo['ftp1.server.com']}/{$serverInfo['For_Web/Web Images/Full Size/00-99/file']}");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($curl);
fwrite($fh, $result);
fclose($fh);
curl_close($curl);`

There are a few problems;
You should open your file for writing in binary mode, that is;
$fh = fopen("test.jpg", 'wb');
curl_exec returns a bool (success), not the contents of the file, the file should instead be passed to CURLOPT_FILE.
You should set the username/password using CURLOPT_USERPWD, not sure if the URL way could be made to work too, though.
You should set CURLOPT_BINARYTRANSFER.
Working sample;
$curl = curl_init();
$fh = fopen("fips.exe", 'wb');
curl_setopt($curl, CURLOPT_URL, 'ftp://ftp.sunet.se/pub/FreeBSD/tools/fips.exe');
curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_FILE, $fh);
curl_setopt($curl, CURLOPT_USERPWD, 'anonymous:olle');
$result = curl_exec($curl);
fclose($fh);
curl_close($curl);
