Integration of a zoom (magnifier) into Colorbox – how?

Hello.

There is a gallery on the site that opens in Colorbox. The problem is that I need to add a zoom (magnifier) effect to the image opened in Colorbox, like here joseprio.com/examples/colorbox/

It works fine on plain HTML, but not in Drupal. I am new to this CMS, so I ask for help. Maybe this can be done using built-in methods that I don’t know about.

Thank you in advance!
