That would be feasible in the web view of the messages. The reply would
have the URL of the original image placed in its HTML <img> element,
replacing whatever src reference it had on arrival.
When the reply is sent out to members by email it may be best to leave
the quoted image as it was received, to avoid the various ills
associated with sending it as an https access.

Different types of difficulties, but yeah.
Were Groups.io to store a hash value with each image it ought to be
pretty straightforward to see if any image file incoming in a reply
matches an image file already stored in this group (or topic).
