Button 2 includes a special class for adding fancy corners to images in your posts and pages.
First, add an image to your post as you normally would.
Switch to the Text Editor and look for the image’s HTML code. It will look something like this:
<img class="alignleft size-medium wp-image-123" ... />
We’re interested in the class portion of the code, shown above. Add a class of fancy to the class attribute, like so:
<img class="fancy alignleft size-medium wp-image-123" ... />
Preview your post; your image will appear with fancy corners, like this one:
Pretty neat, huh? You can even add fancy corners to captioned images!

But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful.
