Resize image during upload

Resize images during upload. I'm using RSComments. This component has the ability to upload an image with every comment.

In the file controller.php there's a function that does the uploading: function uploadfile() (line 95 - line 181).
In this function there must be a check if the imagefile is wider than 500px and if so, scale it back to 500px. I think it is important you have a good understanding of how Joomla 2.5 works. So please check the attachements to make sure this job is suited for you. Attached are the actual php page controller.php and the component itself.

Example of what lies ahead of you:

[part of the function uploadfile()]
$dest = $uploadFolder.$filename.'.'.$ext;

JFile::upload($src, $dest);
[/part of the function uploadfile()]

Should become something like:

[part of the function uploadfile()]
$dest = $uploadFolder.$filename.'.'.$ext;

list ($width) = getimagesize($src);

if ($width > 500) {

$newWidth = 500;

list($startWidth, $startHeight) = getimagesize($src);
$newHeight = $startHeight * (500 / $startWidth);
$newHeight = (int) $newHeight;

$src2 = imagecreatefromjpeg($filename);
$thumb = imagecreatetruecolor($newWidth, $newHeight);

// Resize
imagecopyresized($thumb, $src2, 0, 0, 0, 0, $newWidth, $newHeight, $startWidth, $startHeight);

imagejpeg($thumb, $src2, 0, 0, 0, 0, $newWidth, $newHeight, $startWidth, $startHeight);

JFile::upload($src2, $dest);
} else {

JFile::upload($src, $dest);

}
[/part of the function uploadfile()]

tried it, but it didn't work ;-))
