add file to $_FILES array by reading remote file - php

Question

I'm pretty new to php and we're trying to write a plugin for wordpress. We have a server with images on it and we'd like to have the plugin have a list of images to download from the server. It then needs to go through that list and read each image from the server into the $_FILES variable that we can then pass to the wordpress media_handle_upload function.
I've been able to read a remote file with the following code. But I'm not sure where to go from here.
$url = 'http://www.planet-source-code.com/vb/2010Redesign/images/LangugeHomePages/PHP.png';
$img = curl_init();
curl_setopt($img, CURLOPT_URL, $url);
curl_setopt($img, CURLOPT_HEADER, 1);
curl_setopt($img, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($img, CURLOPT_BINARYTRANSFER, 1);
$file = curl_exec($img);
curl_close($img);
$file_array = explode("\n\r", $file, 2);
$header_array = explode("\n", $file_array[0]);
foreach($header_array as $header_value) {
$header_pieces = explode(':', $header_value);
if(count($header_pieces) == 2) {
$headers[$header_pieces[0]] = trim($header_pieces[1]);
}
}
header('Content-type: ' . $headers['Content-Type']);
header('Content-Disposition: ' . $headers['Content-Disposition']);
$imgFile = substr($file_array[1], 1);
echo $imgFile;

Solution: Lookup table
Create images name list or image file path(link) list as json,xml or txt format. so it will act like as lookup table. it can be parse easily (just like RSS feed customization). call the json or xml file and get the data in the form of array. now you can process it easily
