Answer 1

Is this what you're looking for?
I've made a pure CSS solution that should work up to IE8. :)
Also, it should work with any width/height.
.image-background {
background: #000;
display: table;
width: 100%;
height: 100%;
position: relative;
}
.image-container {
display: table-cell;
vertical-align: middle;
text-align: center;
margin: auto;
max-height: 100%;
max-width: 100%;
}
img {
display: block;
max-height: 100%;
max-width: 100%;
margin: auto;
}

Good luck!

Answer 2

Your div is 400*400, but your image is small, When you have used img-responsive that means img max-size : 100 %. But here you want to see min-size:100%.
You can try below code
<img src="image.png" class="img-responsive full-width" /> <!--add class full-width-->
in your css file
.full-width{
width:100%;
}

Answer 3

Use below CSS,JS and HTML markup to achive this:
<style>
.img-container {
width: 400px;
height: 400px;
background-color: black;
position:relative;
}
.img-container img {
position:absolute;
top: 50%;
left: 50%;
}
</style>
<script>
$(document).ready(function() {
debugger;
var img = $('.img-container img');
img.css('margin-top', - ($('.img-container img').height() / 2) + 'px');
img.css('margin-left', - ($('.img-container img').width() / 2) + 'px');
});
</script>
<div class="img-container">
<img src="http://www.gstatic.com/webp/gallery/1.jpg" class="img-responsive" />
</div>

Here is a stripped-down version of what #Himechi90 wrote.
If you only need one image instead of a row, basically all you need is:
.image-full-view {
float: none;
padding: 0;
background: #000;
display: table;
width: 100%;
height: 100%;
}
.image-full-view img {
display: block;
max-height: 80vh;
max-width: 100%;
margin: auto;
}
<div class="image-full-view">
<img src="https://media.usfcvast.org/images/cvast-arches/projects/la_mancha/la_motilla_del_azuer/la_motilla_del_azuer_aerial.jpg" alt="" />
</div>

Answer 5

You can use object-fit: contain;
css:
.image-container {
overflow: hidden;
height: 16rem;
background-color: black;
width: auto;
}
.image-item {
object-fit: contain;
height: 100%;
width: 100%;
}
html:
<div class="image-container">
<img class="image-item" src="images/Screenshot(1).jpg">
</div>
