Change image with button next/previous in a Scroll View in Unity3d

Question

How do I change the next image with buttons while images are loading dynamically in Unity3D using C#.

 public void NextPictureInGallery()
    { 
        int i=0;//index of image
        if(i + 1 < image.Length)
        {
            i++;
        }
     }

Images are in a Scroll view

@RasaMohamed I put a few lines and an image to describe what I want to do — Ciprian Jijie, Jan 18 '16 at 14:22

You can change the normalized position of your ScrollRect.
