trying to save files to server via a form

[Bobafart]

i am trying to build a form where the user inputs an image from a weblink or an upload.

the form code is:

<form action="" method="post">
	<p>You can either upload an icon or you can point us to a weblink.  The jpeg, gif or png file will be resized to 25 x 25 pixels.</p>
	<p>Weblink Pixel Icon: <input type="text" name="pixelURL" size="55" value="http://"></p>
	<p>OR</p>
  <p>Upload Pixel Icon: <input type="hidden" name="MAX_FILE_SIZE" value="100000" /><input type="file" name="uploadpixelURL" size="44"></p>
	<p>Step 2:</p>
	<p>Now all you have to do is enter the web link you want the traffic to go to:</p>																																	
	<p>Destination: <input type="text" name="destinationURL" size="55" value="http://"></p>
	<p><input type="image" name="confirmPixelBuy" src="http://www.foo.com/img/icons/icon_claimmypixels.gif"></p>
</form>

if(isset($_POST['uploadpixelURL'])){
        // user decided to upload a pixel using var $uploadpixelURL
       	if($_FILES['uploadpixelURL']['type']=='image/jpeg'){
         	$fileext = '.jpg';
	}else{
 		$fileext = '.gif';
	}
	$newname = $_SESSION[userid].'_'.md5(rand(1,1000)).$fileext;
        if(move_uploaded_file($_FILES['uploadpixelURL']['tmp_name'], $target_path)) {
            chmod($target_path,0777);
	}else{
	    echo "<p>There was an error uploading the file, please try again</p>";
	}
	copy($pixelURL, $target_path);
	$filename = $_FILES['uploadpixelURL']['tmp_name'];
        echo '<p>filename is:__ '.$filename.'</p>';
       rename($filename, $newname);
	$pixelURL = 'http://www.foo.com/img/pixelate/'.$newname;
	echo '<p>pixelURL is:__ '.$pixelURL.'</p>';
}else{
       // user decided to save a weblink for the pixel, so save it locally to server
	copy($pixelURL, $target_path);
}

if i try to upload a file the error i get is:

pixelURL is: http://

uploadpixelURL is: coke.gif

destinationURL is: http://www.coca-cola.com/glp/d/index.html

There was an error uploading the file, please try again

Looks like your server prevents the copy function from accessing external urls. You might have to use the CURL library: http://us2.php.net/curl

I haven't worked much with CURL so I can't give you an example.
