How on earth do you expect this to work? Why do you believe it's OK to
cast filebuf* to char*?

You are sending contents of some random memory block to the client. You
haven't read a single byte of data from the actual file yet.

If you just want to send contents of a file on disk as is, see
CHttpResponse::TransmitFile.

Alternatively, if I create read the data into a buffer like this it
works:

Well, duh.

Is it possible to display the image using rdbuf()

No.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
