Designing a Cover

I have segmented all of the tasks that need to be done into smaller chunks and today I am tackling the issue of what the heck to put on the cover of the book.  I am actually leaning towards just using the website design but using one of my own photos instead with the font. 

So....  my next question...   how / who to list as the author?  Do I put all 16 of us?  Do I list one person as the main?  and then everyone else???  Do I just do a contributors list?   So confusing  :/
