The Gmedia gallery plugin on Worpress creates a separate page for each photo, is that bad? How to cancel?

Question

Search Engine Optimization

Hello, a Wordpress site needs a gallery, I installed Gmedia gallery, it creates a separate page for each photo, for example .
They say it's bad, right?

Why are they on the site and what value do they represent in the Google index? By a large number of pages - in principle, you can draw some conclusions about the site, its content, usefulness, etc. These pages are like auto-generated, not created for people.

How to remove them, how best to do in this situation?

Answer 1

Is it necessary to use this gallery? I got rid of this problem by installing envira gallery. All attachment pages are redirected to the page they are located on.
