Gani Help

[IAMNOTAFREAK]

I'm sure this has been explained a hundred times on this forum, but it would take forever to sift through every post that contained the word 'gani' so I'm not even going to try...
anyway, like the topic says, I need help with ganis...

What I know:
-how to add pic to the list on the left
-how to layer the pics

What I need to know:
-how to add many pictures into the gani and be able to change them during gameplay (an example would be the water status for the trees on 2k1 and 2k2)
-how to use the def param thingy
-how to make cutscene with graalshop (i can't find the darn button that's supposed to be there :/ )

that's all i can think of right now...I'm sure there's more, though...
