When is a GIF Finished Playing?

[Ray]

Hi Scott - In my case I let my users decide how many times the GIF 
cycles, so it more than likely will be more than once through, but not 
infinitely as in -1.  I like your second option, below, but how are you 
getting the GIF's frame delay?  Did I miss that Livecode property somewhere?
