It doesn't work. Let me describe again the problem.
Click Add New slide button.
Chose gallery from the drop down menu
Chose gallery Directory /images/stories/.....
Save.
In the panel you will see the word Article (not Gallery)
Click Save and close button.
Open again the module. In the panel "Your slides" you will see the word Text(not Gallery or Article).
Open slide for edit. In the drop drop down menu appears Text option, nevertheless you have chosen gallery option before save. There is even no option gallery in the drop down menu.
In the fronted you can see only gray square and rhombus instead arrows.
That's all. I can attach screenschots if necessary but you can see if repeat above description.

Stoicho
