Just looking at them now, that sort of detail is required so don't worry
about the size of the images :)
However, you may like to compare your pics to those in the h2200-port
wiki pages (taken by Joris). I'm not sure if it's the lighting,
angle, or camera used, but his are a lot more readable.
eg. I cant see dram or even cpu. Are they under the covers? or on
the other side of the board?
The only chips I could really see from your pics are:
ST3243EB http://www.st.com/stonline/books/pdf/docs/8648.pdf
TXC22 ... which _seems_ to be a Panasonic IR controller (IMO)
I would suggest trying to take small sections of the board at a time
(with good lighting) from directly above so that everything in view
is in good focus. I must admit that I am incapable of doing this
sort of detail as I only have a 300K camera :).
 Perhaps you'd like to ask Joris how he did his?

Talk to Joris & Jamey.

Pics of both sides of the board would be good.
