Many thanks for the reply, Robert. After researching
some more and hazarding some guesses, I overrode
NSTextView's writablePasteboardTypes: and set
NSTIFFPboardType as one of the pasteboard types, then,
as you suggested, I overrode
dragImage:at:offset:event:pasteboard:source:slideBack:,
and added the following code:
[pboard setData:
[[[[self textStorage]
attribute:NSAttachmentAttributeName atIndex:0
effectiveRange:nil] fileWrapper] regularFileContents]
forType:NSTIFFPboardType];
This works great - I can now drag a picture from the
text view into the image view. Obviously, this is test
code, and only works if the picture is the first
character in the text view (atIndex:0), so I have to
refine it to work for the selected range. But the
refinement is fairly minor now that I have got the
basics working.
So many thanks again for giving me pointers on where
to start!

I don't know if it will work, but it is the first
thing I would try.
