Popular Albums Widget

Can someone explain when the popular albums widget show up?
I've added it on my main time line, but I don't see any album pics displayed (the complete widget is not displayed..).
I have set that everyone can see the widget

I'm sure that I have pics on my network which have been displayed a lot of time (also added with comments or likes) but they are not displayed in the widget.

I think popular are the ones with the most appearances
But there is nothing to measure how many appearances she has, and I can not figure this out
That is, I want to say, based on its popularity, but from which it draws that data
