Animation Direction

Does anyone know how to make Image Image Show GK4 continue to slide one without backing up through the previous slides?

Currently it goes slide 1, 2, 3 then 3,2,1. I would like it to display as:

Slide 1, 2, 3, 1,2,3 without stopping.

Right now there is no such possibility.

But there is smart idea.
Just add picture 2 (slide with picture number 2) using different name after number 3, so you will get quite similar effect as you asked.

1,2,3,2,1,2,3,2.... easy

Thanks for the suggestion.
