You want an image to appear where site icons appear on browser tabs? Open the customizer, go to the Site Identity panel and set your image as the site icon. If your image is not square, you’ll be asked to crop it. This will not affect the original image.
Hi,
I made an example I’d like to achive:

I’s using different Tab-plugins but none has function I need.
If you are using a plugin to generate tabs, it may not be possible to place actual images. You may be able to place font based icons like those from fontawesome.com. If you can place <i> tags in tab labels without them appearing as plain text, you can use fontawesome.
A more generic solution for font based icons is to insert content before the tab label container with CSS’ :before pseudo-selector. You could use the built-in dashicons to do this. The font is only loaded automatically for the admin area, it needs to be explicitly enqueued for front end use.
wp_enqueue_style( 'dashicons' );
