Align a row of images in Sketch

I’m using Sketch as my theme for javidiaz.com
I have a a main page which is using the portfolio feature and aligns to the center of the website. I have a few pages which are full width pages but the images all align right. Has anyone had success centering a row if images to the website? If I use align center, the images align on top of each other in a single column. Thanks for any help.
