How to create a image-wheel?

Hello fellow creative people,

im in the making of an android app with ue4.10.
The app doesnt feature a real game with 2d/3d movement, it is more a widget umg based app for showing image based tutorials and presenting stuff.
i know there are ways to create these kind of apps w/ a game engine and in terms of space consumption and so on, but i tried pure gradl eclipse and android studio before and had trouble with programming.
i stumbled upon the blueprint system in ue4 and started working.

As i said before, most is image umg based but i want a certain feature:

the user is able to choose pictures (between 1 and ca 25 via a toggle button) and then after he confirmes his selection there should pop up a new widget with a image-wheel, which runs throu the selected images (randomly put in order and also appear multiple times)
if you know the spinning animation in csgo, thats how it should look like, but instead of skins i want pictures

any idea on how to start?

tried it with arrays so on the togglebutton event it adds the image to a array and when user tabs on go an other widget gets the array and displays them randomly and repetetive side by side and runs them throu

thy for your answers
