 @cindex image animation
-Some image files can contain more than one image.  This can be used to
-create animation.  Currently, Emacs only supports animated GIF files.
-The following functions related to animated images are available.
+@cindex image frames
+Some image files can contain more than one image.  We say that there
+are multiple ``frames'' in the image.  At present, Emacs supports
+multiple frames for GIF, TIFF, and certain ImageMagick formats such as
+DJVM@.
+
+The frames can be used either to represent multiple ``pages'' (this is
+usually the case with multi-frame TIFF files, for example), or to
+create animation (usually the case with multi-frame GIF files).
+
+A multi-frame image has a property @code{:index}, whose value is an
+integer (counting from 0) that specifies which frame is being displayed.
+
+@defun image-multi-frame-p image
+This function returns non-@code{nil} if @var{image} contains more than
+one frame.  The actual return value is a cons @code{(@var{nimages}
+. @var{delay})}, where @var{nimages} is the number of frames and
+@var{delay} is the delay in seconds between them, if the image itself
+specifies a delay.  Images that are intended to be animated usually
+specify a frame delay, whereas ones that are intended to be treated as
+multiple pages do not.
+@end defun
+
+@defun image-current-frame image
+This function returns the index of the current frame number for
+@var{image}, counting from 0.
+@end defun
 
-@defun image-animated-p image
-This function returns non-@code{nil} if @var{image} can be animated.
-The actual return value is a cons @code{(@var{nimages} . @var{delay})},
-where @var{nimages} is the number of frames and @var{delay} is the

+@defun image-show-frame image n &optional nocheck
+This function switches @var{image} to frame number @var{n}.  It
+replaces a frame number outside the valid range with that of the end
+of the range, unless @var{nocheck} is non-@code{nil}.  If @var{image}
