Answer 1

You are aware, that if you are receiving an Base64 encoded image, as a string, then you do not need to use the Upload class.

Instead, you just need to decode it using base64_decode and then use fwrite/file_put_contents to save the decoded data...

$img = imagecreatefromstring(base64_decode($string)); 
if($img != false) 
{ 
   imagejpeg($img, '/path/to/new/image.jpg'); 
}
