"Centering" images with bootstrap's grid

Explanation

I trying to "center" 3 images with Bootstrap's grid class col-lg-3 (>=1200px), but for some reason, when using a 273x303 image, it doesn't center; however, it does with a 670x670 one, as you can see in the code below.

Am I doing anything wrong? I got kinda confused since 670x670 works great.

Code

273x303

You can also see it's fiddle.

.main {
    background-color: blue;
    position: relative;
}

h2 {
  color: black !important;
}

h4, span {
  color: red !important;
}

Try adding display: initial; to the .img-responsive class. The snippet below has been updated.

NOTE: The use of !important is not required.

.main {
    background-color: blue;
    position: relative;
}

h2 {
  color: black !important;
}

h4, span {
  color: red !important;
}

.img-responsive {
   display: initial !important;
}

Utilize the .center-block class in bootstrap on the images to center them. That will apply a left/right margin of auto, which will center the block element that results from using .img-responsive

.main {
  background-color: blue;
  position: relative;
}

h2 {
  color: black;
}

h4,
span {
  color: red;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<section class="main">
  <div class="container">
    <div class="row">

      <div class="col-md-12 title text-center">
        <h2>273x303</h2>
      </div>

      <div class="col-lg-4 master text-center">
        <img class="img-responsive center-block" src="http://i.imgur.com/3Eqr1Gf.png" alt="Blog Post">
        <h4>testing title 1</h4>
        <span>testing subtitle 1</span>
      </div>

      <div class="col-lg-4 master text-center">
        <img class="center-block img-responsive" src="http://i.imgur.com/3Eqr1Gf.png" alt="Blog Post">
        <h4>testing title 2</h4>
        <span>testing subtitle 2</span>
      </div>

      <div class="col-lg-4 master text-center">
        <img class="center-block img-responsive" src="http://i.imgur.com/3Eqr1Gf.png" alt="Blog Post">
        <h4>testing title 3</h4>
        <span>testing subtitle 3</span>
      </div>

Class .img-responsive from Bootstrap already sets display: block, you can use margin: 0 auto to center.

Add this line:

.master .img-responsive {
   margin: 0 auto;
}


.main {
    background-color: blue;
    position: relative;
}

h2 {
  color: black !important;
}

h4, span {
  color: red !important;
}

.master .img-responsive {
   margin: 0 auto;
}
