Added Videos to the Why page

Added 3 more videos to the "Why" page. Tried to space them out so the
original picture could show. I might change the spacing again.
Repositioned the Videos

I like the position of the videos better now. They are at the 4 corners
of the page.
Added Brain Photo to "Gain" page

The brain photo is there. Might want to play with the background color,
so the page isn't so black.
Finalized the Images

All intended images are added and sitting well. Changed the link color
on "Who" page.
