Is it possible to shrink the middle image (using flex-box) such that when the content in header, footer grows it shrinks such that the total content height of flex children (header, footer, img-wrap) does not overflow out of parent container?
Current view of layout in 
Any help is appreciated. Thanks.

I don't often resort to absolute positioning, but it works here on the image container, which is now inside the flex child. Note that non-static positioning must be set on the parent element as well.
Also, instead of wrestling with flex-grow and -shrink values, I just use flex: auto and flex: none on the various flex children. It isn't necessary to use it in all cases, but it makes the layout's behavior more intuitive to me when I see it in the CSS.

You may use display: grid for this one.
Check the object-fit: cover; for the image so that it doesn't squeeze and with this solution, the image stays centered and isn't just cut below.
Does this work with my pen? https://codepen.io/maki3000/pen/BamgxaB?editors=1100
