I need an icon!

I would really like an icon for my resurrected!John 'verse (3rd story rough draft just completed, by the way...woo hoo!), but I have no idea where to go looking for one. Does anyone know of any good places to look? I'd really like one with John and the boys in it, but I'm just terrible at this sort of thing and have no idea if such an icon exists or whether all three of them would even fit in the little square.

Visually artistic, I am not.

Hope you all had a good weekend! Thanks for any icon suggestions. :)
