As far as it is consistent throughout all the tracks displayed in LFS Manual, go the way you like the most.
I'd prefer a more "schematic" way than a "photographic" one, maybe the old, white, style was more kind of "direct", but it's just a matter of personal taste.
If you choose to go with the new graphics (taking WE1.jpg as an example), I'd like if the configuration's name stood out a bit more...more contrast, or a slight bigger font.
