I am having some trouble resizing in responsive way two of the images in this page

Hi everybody. I am looking to find how I can resize responsively a couple of the images on this page. It is a kind of digital business card design for a sales team.
My trouble begins when the page is being resized manually to see how it fits in differents resolutions, the image of the sales person and the QR code moves along the way but they don´t resize accordally. The breakpoints have been set as well it has been designed using divs and absolute positions.

I appreciate any help!!
