Slide show with Three buttons on one screen

Hello,
I am making an educational app. In which I want to make a slide show with three buttons (Play, Previous and next) of the images on one screen.
Can anyone please help how this can be done.

Make a list of your images, and a variable. When previous clicked, set the variable to variable -1, then set the image to select list index using the variable.
When next clicked, set the variable to variable +1 , then select list using the variable again.
When play clicked, use a timer. When the timer fires, add 1 to the variable and do the same thing.

Thank you Dear, I will try this out. :slightly_smiling_face:
