When is a GIF Finished Playing?

If you want the GIF to stop playing when it reaches the last frame, why
wouldn't you set the repeatCount to 1?
If your GIF can play multiple times through (repeatCount = -1), then I
believe the only way you can track its frames is to poll it, with a
frequency that slightly exceeds its frame delay. Try running a loop while
the GIF is playing, maybe something like:
# GIF WITH 10 MS FRAME DELAY
set the repeatCount of img "myGif" to -1
if the currentFrame of img "myGif" > (the frameCount of img "myGif" - 1)
set the repeatCount of img "myGif" to 0
set the currentFrame of img "myGif" to the frameCount of img "myGif"
-- just to be sure
send "trackPlayback" to me in 8 millisecs
