This is what I use for Screenshot Sender 4. If you choose to keep the script you must keep the header regardless if you change the file or not.
This script is going to be apart of the snippets that will be available on
http://mpscripts.net
For now its hosted on my server.

Note : If there are any errors with it please PM me. As well I am going to be changing the functions around a bit so I will update the file on my server and the latest one will be on
http://mpscripts.net when we get enough snippets made.
