I have filed a Radar on your bug. :)
rdar://4396965 [Finder] Cannot display pictures in RTFD text
clippings
Open TextEdit. Inside TextEdit, create or open a document that
contains a picture. (I found that this is pretty easy to do by
dragging a picture from Safari into TextEdit.)
Drag the picture from the TextEdit document onto the desktop. You will
now have an "Untitled clipping.textClipping" file. Double-click it and
you will see an empty window--no text, no pictures. However, the text
clipping does in fact contain a picture--if you drag it back into
TextEdit (or another app like Stickies), it works as expected. The
Finder is just not correctly rendering the RTFD data.
The Finder needs to fully support RTFD display in its clipping preview
pane. Cocoa has excellent support for automatically loading and
displaying RTFD; the Finder needs to leverage this.

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?
