How to Add Slider in Wordpress Post?

Actually, I am creating a post and I have to use almost 20 to 25 images on it. If I place it one by one than it takes too much space and if i make Gallery then it shows vertically (in columns) but i don’t want this. I want to make a slider with next and previous button to see all the pictures.
I hope you will understand what I want to make? Waiting for your reply and I am sure you will give me the solution of this problem.
