Texts overlaps image on resizing Bootstrap - html

Question

I am new with Bootstrap and css. Help out a newbie. When it is maximized, I have a layout that I want but when I re-size it to a smaller size, the texts overlaps the images on top of it. Your help is very much appreciated. Here is my code:
<section id="work" class="container">
<div class="page-header">
<h1 class="text-center">My Work</h1>
</div>
<div class="text-center">
<img src="images/portfolio1.jpg" class="img-thumbnail">
<img src="images/portfolio2.jpg" class="img-thumbnail">
<img src="images/portfolio3.jpg" class="img-thumbnail">
<img src="images/portfolio4.jpg" class="img-thumbnail">
<img src="images/portfolio2.jpg" class="img-thumbnail">
<img src="images/portfolio1.jpg" class="img-thumbnail">
</div>
</section>
<section id="about" class="container">
<h2 class="text-center">About Me</h2>
<div class="col-text text-justify">

Answer 1

The issue is that you need to wrap each image in a bootstrap column so that they resize properly without interfering with each other.
<div class="row">
<div class="col-md-6">
<img src="images/portfolio1.jpg" class="img-thumbnail">
</div>
<div class="col-md-6">
<img src="images/portfolio2.jpg" class="img-thumbnail">
</div>
<div class="col-md-6">
<img src="images/portfolio3.jpg" class="img-thumbnail">
</div>
<div class="col-md-6">
<img src="images/portfolio4.jpg" class="img-thumbnail">
</div>
<div class="col-md-6">
<img src="images/portfolio1.jpg" class="img-thumbnail">
</div>
<div class="col-md-6">
<img src="images/portfolio2.jpg" class="img-thumbnail">
</div>
</div>
