edit: layout is: parent div image div child. parent div's height defined @ 600px , width @ 100%. , height , width of image div defined 100%.

assuming desired width/height , overflow: hidden applied outer containing div, can add like:

.container img {   position: relative;   top: 50%;   transform: translatey(-50%); } 

this move displayed area of image down 50% of container height (top: 50%), 50% of image height (transform: translatey(-50%)), ends centering inside container.

you can adjust these values achieve different positioning, or add in left: , transform: translatex() adjust horizontal axis.
