avatar alignment

Hi Paul. Great plugin. I must be one of your longest term users. Been several years. Anyway, awhile back, I tried to upgrade my theme to a newer version studiopress genesis theme, but it knocked my avatars out of alignment. They display diagonally instead of as a grid. This can be seen at http://newyorkcity.urbdezine.com. Any fixes?
