Is it justified to put hidden elements in some places of the code for SEO?

Question

HTML

Good day.
There is a slider in which, due to the possibility of automatic scaling, the slides are ordinary divs with a background image. Is it worth it to shove a hidden (moved under the slide through the z-index) img with the alt attribute specified so that the pictures of the slides are displayed in, for example, image search? Or for it can knock?
Thank you.

Google is not a fool - such chips have been firing for a long time.
