Hi John
I noticed that when dragging only an image from the textview to the
finder the finder produces a text clipping. I had been hoping for
more intuitive behavior from the textview that would place tiff data
on the pasteboard as well when (only) an image was being dragged.
Looks like I need to override some the dragging methods then and
check for the presence of a text attachment in the selection before
actually writing to the pasteboard.

I think it will drag out RTF data with the image embedded in it (as
an NSTextAttachment). So the image is there--it's just that not all
apps that are expecting pictures will accept it.
It's certainly possible to extract the image back out, if you have
control over the drag target.

Ah, please excuse me. In all the excitement of the question I
wrote nstextfield instead of nstextview. I am talking about a
text view. It just seems really strange that the view can handle
an image drag in but not a drag out.

Is it really the case that dragging an image outside of an
nstextfield only produces a text clipping and not the image
itself? Does the text field not automatically place, say, tiff
data on the pasteboard? Must it be that I have to override the
textfield's dragging methods in my subclass to produce the
proper pasteboard data? Could the whole situation be any more
melodramatic?!
Seriously though, is there an easier way to get image data onto
the drag pasteboard when a user drags that kind of data out of
my textfield subclass, or am I going to need to override/
implement a few dragging methods?
