Use this page as a sample for your home page. This page has all of the coding used on the home page.
To change the timing on the fade in images, look for this type of coding:
Change the .8 to a larger value to increase the delay or a smaller value to have the image/box/title come in more quickly.
Make sure you use the class of "imgBox" for your images larger than 250 pixels. This way they shrink as your viewport shrinks.
You can link the images or add text underneath each one as I've done below. I used an "h2 alternate" and "h2 alternate2" to style them.
