Lotus Notes Agent - Remove Embedded Images? - lotus-notes

Question

I have an agent someone shared years ago which takes attached files, saves them to my hard drive, and removes them from the email. I use it to keep my emails for a while but stay under my corporate mailbox quota. I get a LOT of attachments.
I'm now finding that a lot of the remaining large emails have embedded images rather than "attached files". Can anyone share a script that would actually be able to do the same (save to hard drive, remove from email) with an embedded image?
FWIW, here is the agent I use for detaching attachments. Props to original author, don't know who that was.

This is very problematic to do with the script as it currently stands as MIME encoded images won't show up as any type of attachment using the EmbeddedObjects Property.
If the images are stored inline as part of a MIME message, the Notes client will turn them into an attachment for viewing, but programmatically the can only be accessed as parts of the MIME message. It should be achievable to grab the correct part of a multi-part MIME message with the image encoded (using the MIMEEntity classes), stream this out to disc and reconstitute the original file(s) then remove the MIMEEntity that represented it (and took up the space).
