Hi Lori -
I'm super-new, also working on the initial portfolio project. (It's a mess right now.) But I did learn and successfully implement the code for making your image round.
--Sorry I don't know how to write this with the <> without the editor thinking I am trying to add an image, so you'll have to imagine them there--
img class="img-circle" src="# "
You can also put both classes together like this:
img class="img-circle img-responsive" src="# "
You can click on the MAP button in the header and review lessons for clues too!
Wishing you success!
