The current versions have these features:
Here's the 1.0.2-compliant source code. (Here's the 1.1-only source code.) You can save the source code by bringing up the View Source window for it, and clicking the Save button. Then compile it (with javac, the Java compiler) and try it out.

The Animator applet isn't finished -- we plan to add more features -- but we'd appreciate your suggestions. Send bug reports and feature requests to java@java.sun.com.
You can get a bunch of information about Animator by pressing the SHIFT key while clicking the mouse in an Animation.

STARTIMAGE and ENDIMAGE let you specify a range of images. Specifying an ENDIMAGE that is numerically less than the STARTIMAGE will display the images in reverse order. Both parameters have default values of 1, so specifying only STARTIMAGE="15" means "play the frames in reverse order from 15 to 1." Saying only ENDIMAGE="13" means "play the frames from 1 to 13." Of course, you can use both STARTIMAGE and ENDIMAGE together.
NAMEPATTERN lets you specify how to generate the names of the files in the range STARTIMAGE to ENDIMAGE. The pattern is like a URL with substitution. Any instance of the characters '%N' will have the current index (integer in the STARTIMAGE..ENDIMAGE range) substituted for it; any instance of '%[digit]' -- for example, '%5' -- will have the index plugged in, left-padded with zeroes. Finally, '%%' substitutes a single '%'.
Some examples (all assume STARTIMAGE = 1 and ENDIMAGE = 10):
