Trying to add play pause button and to fix continual left/right rotation using JFLOW

I have a rotating banner that uses JFLOW, on this it has a left, right, and the image container numbers, and it continually rotates.

But I would like to add a PLAY/PAUSE function

Plus have it continually scroll one direction after the last slide, instead of after the last slide stop and scroll left and reset?

Any assistance would be appreciated.

Please see attached

Thank you
