By default, images don't have any borders:

But if you want they can be framed:

<p>
<img class="image-with-border" src="lotus.jpg" />
</p>
Or they can have shadow:

<p>
<img class="image-with-shadow" src="lotus.jpg" />
</p>
Or they can even have overlay:

<p class="image-overlay">
<img src="lotus.jpg" />
</p>
Border-radius

Image Lightbox
It's possible to open a larger version of the image in the lightbox:

<p>
<a class="image-with-lightbox" href="lotus.jpg">
<img src="lotus.jpg" width="400" />
</a>
