 Interoperable image import

+An interoperable image import process is introduced in the Image API v2.6.
 
-*This EXPERIMENTAL API is optional and may not be enabled in your
-cloud.  Consult your cloud operator's documentation for details.*

-In version 2.5 of the API, these calls return a 404 (Not Found).
-Use the :ref:`API versions call <versions-call>` to determine
-what API verisons are available in your cloud.
-
-.. note::
-   This EXPERIMENTAL API is subject to change.  It is a partial implementation
-   of what's described in the Glance design document `Image Import Refactor`_.
-   We expect any changes to be expansive and to be in accord with what's
-   described in that document, but we are releasing version 2.6 in
-   EXPERIMENTAL status in the Pike release so that we can reserve the right to
-   make backward-incompatible changes in light of feedback from users and
-   operators.  Our intent is that these calls will be finalized before the
-   Queens release and the EXPERIMENTAL status will be lifted at that time.
