Use triggers and variables to cycle through multiple layers in sequence

Hello,

I have 73 images that I want to show in sequence to animate the wrapping function for the unit circle.  I know that there are several ways to do this, but I'm not sure which is most efficient and easy to replicate.  I have created a .story file to test the different methods using only 6 images.

As far as I can tell, here are my options:

• Option A  Create a slide with a layer for each image and create a trigger that displays the layers in sequence (see slide 1.3 Layer_TriggerShowLayer)
• Option B  Create a slide with one image and create states for each of the other images.
  • Option B.1  Use a slider to show the states in sequence, which is easy to setup. However, I cannot figure out how to make the slider move automatically through every state using triggers based on the timeline.  I would love to have the states appear in 1 second intervals.  I’m not sure this is even possible (see my attempt on slide 1.1 States_Slider)
  • Option B.2  Use triggers and timeline markers to move the states in sequence (see my attempt on slide 1.2 States_Trigger_Timeline)

The best effect so far is Option B.2, but it will require a lot of timeline markers to make all 73 images appear.  Is there a way to do this using a variable that is linked to the timeline?Or maybe one of the other methods will work better with some tweaking?

All advice is appreciated.  I am also happy to watch any training videos that may help me make this smoother.

Thanks in advance!
