Be able to disable the lightbox effect in the opening of the user cards

I'd like to know how I can avoid the lightbox effect of the photo when I click to open the user card.
Currently, when I want to open the user card, it also opens the popup with the enlargement of the photo (despite not having plugins for this effect in Wordpress). So I've to close the image, close the user card; aesthetically and in practice, they have a terrible result.
Cheers.
