hello. If you are talking about the resort and mtn-landscape images then they were centered using the 

margin: auto;

in the 

.primary-content, 
.secondary-content {
    width: 75%;
    padding-left: 50px;
    padding-right: 50px;
    margin: auto;
    max-width: 900px;
}

hope this helps :)

Hi Elie,

Looks like you'll want to use: 

img {
   max-width: 100%;
}

That will prevent the images from flowing outside of the container element's boundaries and keep it centered with the rest of the content.
