I'm up for working on this, but I've PM'ed you about that as I'm not sure if it's my first priority.
Ya, I responded. This thread is in the public forum, so it's geared more towards the HLP public (i.e. people who aren't already members of SA).
Are there special requirements for screenshots?
If i read about "The Scroll of Atankharzim" i think primarily about screenshots that should contain vasudan ships or technologies.
The idea is that each loading screen will be related to the mission, without giving anything away. Think of the loading screens that are used in Derelict, except whereas Derelict used the same loading screen for multiple missions in a row, Scroll will have a unique screen for each mission.
So, yes, Scroll is Vasudan-based which means it will contain a lot of Vasudan ships. But the intent is not to create a random screenshot with random Vasudan ships.
