Image blocks have an ability display round images. It’s a big, easily identified setting, but most people don’t use it most of the time.
Of course overuse of round images would be too much of a good thing.
Combining rounded images with ‘float’ also known as ‘align left’ or ‘align right’ can have a very nice effect in posts with lots of textual content.
In an image block, just click the Rounded button.
Optionally, you can switch back to the Default style, and you’ll see that further down, you can control border-radius in case you’d like rounded corners rather than fully round.
If you’re editing in HTML, simply use border-radius:100%; and float:left; or float:right; like so:
<img src=’whatever.jpg’ style=’float:left; border-radius:100%;’>
