It might use an image property to show an icon _instead_ of a MIME attachment.
Now, if you copy the message to another buffer, do you want to still _see_
the icon instead of the MIME attachment, or do you want to see the "raw" text?

There may also be a mouse action associated with the icon, causing the MIME
attachment to be expanded (or saved or whatever).

I guess, it again depends on what the target buffer is.  If you are composing
a new message, it would make sense to just see the icon for the attachment,
but for other purposes, that may not be what you want...

No, but images are a good example of something which may be problematic, e.g.
it does make sense to copy images between "document" buffers or mail buffers,
but not into a C or lisp buffer.

However, as I tried to explain, some images (e.g. a picture of my cat)
may be "true" images (which are part of the text/document), and other
images may be added by emacs lisp code (e.g. an icon for an attachment).

So I don't think you can make a general rule which will cover both.

I dislike it too, but at least it gives the user the final word!
