New Modder - Trait Modding Questions

[Trickster7135]

Editing traits to suit my tastes, using History in the Making Mod as my base. Here's the things I can't figure out how to do so far:

1. This one should be easy: how do I get a picture up for new traits? I can't for the life of me find where to define trait art.

2. I want to make a trait (charismatic) reduce war weariness by -25%. I'm guessing this would be a python job?

3. I want to make a trait (nautical) increase foreign trade route yield by 50%. Another python job?

4. I want to make a trait (industrious) increase how quickly workers build improvements by +50%.

5. Lastly, and somewhat unrelated, anyone know a unique effect for a Humanitarian type trait? All I can think of is +2 happiness/+2 health and free medic1 type promotion.

EDIT: while I'm here posting about this, I figure I might as well as post my full trait ideas and see if you guys think they're balanced or not. I'm making my traits more powerful than the regular ones are, as I think it makes things more interesting.

[Jarlaxe Baenre]

Charismatic would need to give a free building to all cities that reduces war weariness (A building with no description or civilopedia mention)
Nautical: A building like charismatic but that increases foreign trade
Industrious: I believe that option is in civ4traitinfos.xml, but if not, make a building like the above 2

Financial is underpowered.
Scientific could boost library, university, oxford university, and university of sankore production.

How do you have a trait give a free building?

Also: what would be a good +% for financial for it to be balanced?
