Give any example to create stylish images in Bootstraps ?

Answer:

In Bootstrap css there are some predefined such as image circle , image rounded, image thumbnail.Image circle sets circle frame to the image.Image rounded sets curved border to the image.Image thumbnail sets thumbnail image.
Example :

<div>

         <img src="/DotNetFunda.jpg" class="img-circle" alt="Circular" />

         <img src="/DotNetFunda.jpg" class="img-rounded" alt="Rounded" />

         <img src="/DotNetFunda.jpg" class="img-thumbnail" alt="Thumbnail" />

 </div>

Note :Images which you insert in to "src" should be available in the solution explorer/ in your project file.
