Download an image with php

[lip9000]

Basically I want to be able to run a php script that downloads a thumbnail according to the youtube page that I post.

 

So if I put in this url, I know the exact URL to download the thumbnail from according to the V parameter that it has.

 

http://youtube.com/watch?v=w8etbQnvZm0

 

So from this URL I know the thumbnail URL will be:

 

http://i.ytimg.com/vi/w8etbQnvZm0/default.jpg

 

Also I want the script to download this image to a certain folder such as www.mysite.com/images/thumbnails

 

Does anybody know how I would go about putting this together?

How about:

 

<?php
$url='http://youtube.com/watch?v=w8etbQnvZm0';
list($junk,$v) = explode('v=',$url);
$im = @imagecreatefromjpeg('http://i.ytimg.com/vi/'.$v.'/default.jpg');
if($im){
    imagejpeg($im,'images/thumbnails/'.$v.'.jpg');
    echo 'Image saved to: images/thumbnails/'.$v.'.jpg';
}else{
    echo 'Image could not be loaded';
}
?>
