Answer 1

1.

You have an Image component or Texture2D component

Image image;

// or Texture2D texture;

2.

You have an array of sprites

Texture2D[] mySprites;

3.

for right button click -> i++

for left button click -> i--

image.sprite=mySprites[i];

// or texture = mySprites[i];

I think that's what you are looking for :)

Answer 2

Here its a working script .

public Sprite[] gallery; //store all your images in here at design time
public Image displayImage; //The current image thats visible
public Button nextImg; //Button to view next image
public Button prevImg; //Button to view previous image
public int i = 0; //Will control where in the array you are

public void BtnNext () {
    if(i + 1 < gallery.Length){
        i++;
    }
}

public void BtnPrev () {
    if(i - 1 > 0){
        i--;
    }
}

void Update () {
    displayImage.sprite = gallery[i];
}
