yes the key is to specify the correct contentType param (in this case image=
/jpeg)
and the correct contentDisposition (in this case filename)
inline can be used for small file transfers (under 4k)

<result name=3D"success" type=3D"stream">
  <param name=3D"contentType">image/jpeg</param>
  <param name=3D"inputName">imageStream</param>
  <param name=3D"contentDisposition">filename=3D"document.pdf"</param>
  <param name=3D"bufferSize">1024</param>
</result>
