You: "how do you put the youtube videos and the pictures in your books?????"
Me: After the chapter you post has been published look to the right of your screen and you will seen a box that has icons in them. It's called "writer's tools." There's an icon that says Video, click that and a youtube dialog link will show up. Go to youtube and grab the link of the video. Scroll down on youtube and in the description box section find the "share" tab. Copy and paste that link into the "video" tab link back on wattpad and it should show up.
For the pictures, click on the photo icon in writer's tools and find a photo sharing site that provides the direct link to the picture you want to use, like photobucket.com or imgur.com. You can sign up for imgur.com for free and post pictures up to 225 i think. It also provides direct links for you pictures. Grab them and copy and paste them on the video tab link to you chapter in ur book.
For a video tutorial to use for the picture, i made a video last year demonstrating that: https://www.youtube.com/watch?v=VNdq5vePVyA
