removing metadata on image hover possible?

Hi!

I just created a very simple image blogpage. It contains an image (with reduced brightness on hover) and a link to separate page and nothing else. So the image you click on will take you to the blog post page. So far so good. But when I just checked mobile view on my mobile and I hovered over the image there’s a popup with things I really don’t want to be there. If you look at the images here: https://imgur.com/a/styRyDd you’ll see what I mean.

How do I make that info go away? Is there a plugin or can this be edited somewhere else?

Thank you very much in advance!

Martin
