+Saving multiple MPO frames
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Multiple MPO frames can now be saved. Using the ``save_all`` argument, all of
+an image's frames will be saved to file::
+
+    from PIL import Image
+    im = Image.open("frozenpond.mpo")
+    im.save(out, save_all=True)
+
+Additional images can also be appended when saving, by combining the
+``save_all`` argument with the ``append_images`` argument::
+
+    im.save(out, save_all=True, append_images=[im1, im2, ...])
