skins, sounds and elephants

i have created a unit for the Egyptians based on the Seleucid War Elephant (the un-armoured elephant with archers) and i have managed to get the soldiers on the elephants back to be egyptian, and i have managed to find out how to change the skin in descr_model_battle.txt, but i am stumped on how to make a skin for it (and if i knew, it would probably be shoddy at best). i know it will entail extractions, somehow, and a tga/dds editor(of which i have none). Unit card and unit info pictures editing know how aswell, would be appreciated.:book:

Also how to get the sounds such as when you click the unit "war elephants" "elephants" etc. this is a problem i have with many units, no sounds when i clicked on one (elephant sounds/groans/trumpets work)

thanks in advance to all who help

:help:

if it works i will probably release it (with credits to helping people)
