how to make bootstrap image responsive

Add this at the end of your custom css usually the file called style.css

img { width: 100%; }
you can also use img{display-block; width:100%;}
or
img {
display: inline-block;
height: auto;
max-width: 100%;
}

or
img {
display:block;
height: auto;
max-width: 100%;
}

Whichever works for you. Display block turns the image to a block element and will put it on its own line. Me; I just use img{width:100%;}

That is all there is to it.
