Scrolling through stacked images

I am relatively new to VBA and wanted to write code to be able to scroll through stacked images on a single slide using a scroll bar. After reading many VBA tutorials, I am still at a lost on where to start. I am using powerpoint 2016. Examples of areas where I am lost are - should I add the images in a stacked format to ImageControl? How do I reference images on a powerpoint slide? How do I assign values to a ScrollBar to align with image numbers?

If anyone could point me in the right direction I would greatly appreciate it.
