How to make gif animation?

Question

gif

There are many photos. You need to create a gif animation, like a slide show, so that the pictures change quickly. I know a way in Photoshop when you need to put a picture on each frame - this option does not suit me. We need a simpler and faster way to select a number of photos and turn them into a gif animation with "one action".
