Following the 12 grid system of bootstrap how would I place the image code below in example one below the class jumbotron text-centre
in the centre? How would I use media queries to ensure the image is responsive and fits on all devices and browsers properly?
EXAMPLE 1
<div class="container">
<div class="row">
<div class="col-md-4">
<div class="thumbnail">
<a href="http://i1126.photobucket.com/albums/l611/ldocherty1/IMG_0730_zpsiz4dqc47.jpg" target="_blank">
<img src="http://i1126.photobucket.com/albums/l611/ldocherty1/IMG_0730_zpsiz4dqc47.jpg" alt="picture of me" style="width:100%">
</a>
</div>

As long as your Image has 100% width property, and height auto, your image gonna scale to it’s parent element. So Image size depends on
.thumbnail
parent, which inherits size of it’s parent, which is child of element, that has .col-sm-4 class (that class defines it’s size).refrencing to bootstrap documentation and code samples on sites like http://bootsnipp.com and http://getbootstrap.com/getting-started/ would help you in case you ever get lost in any bootstrap code.
however to make an image responsive on all browser you need to add the class
class="img-responsive"
to the<img src tag
which is same as addingstyle="width: 100%" height: "auto";
to make it responsive, you would pick the major break point and style it just the way you want it to be.
however my advice to you is to utilize all bootstrap tags and class, it ease your job of creating multiple breakpoints, for instance using col-md-12 on medium devices , col-sm-12 on small devices col-lg-12 on large devices.
