How to save image attachment from email using IMAP & PHP?

问题

I've successfully written script that connects to my mail server and retrieves the headers and bodies of all new messages. I want to take it one step further to detect if attachment exists (images only), if so, download to server.

How to go about this using PHP & IMAP?

Thanks in advance
