anatomy of a dogs eye

I have someone whoapos;s going to make me a Frodo for my dolls house in the new year. I donapos;t want him in his Fellowship costume. I want him in his Rivendell nightshirt and Iapos;m having awful difficulty finding images online, although I know theyapos;re out there.

They are on the EE DVD but I donapos;t know how to make screencaps so thatapos;s out.

Can anyone on my flist point me at some pictures?
