I found a great Stackoverflow page that helped me do this: http://stackoverflow.com/questions/11757537/css-image-size-how-to-fill-not-stretch
There are some CSS elements that weren't shown yet, but this worked perfectly and isn't too hard to follow. One thing I did that also wasn't covered to this point is that you can have multiple classes per div. Here is what I mean. Look at line 9 where I have 2 classes for my cousin Jesus.
And here is the CSS where you'll want to look at line 27 where I put the stylings for that particular image fill.
Hope that helps!
