UMG Interactive Gallery (swipe and zooming images)

Hi! I’m Luca, a graphic designer, I’m learning Unreal from June and I’m working on an interactive application based on a simple menu system with a lot of write and media content like images and videos.
Actually I’m trying to implement the Gallery with the swipe by using touch or left mouse button (for change images) and with the zoom by using the mouse wheel or by using two fingers move (for zoomin and out).
I’m newbie and unfortunately I don’t know the C++. This is my gallery blueprint:

Anyway I’m thinking to use for the swipe an Horizontal “scrollable box” but it can’t stop (I think) on a particular image when you swipe.
For the zooming I’m tried to use a lot of tutorial but no one of these works. I need of an image that will be zoomable by scrolling the mouse wheel or by using the traditional two fingers move.
Any Suggestions?
Thank you!
