unit images creation

[hermestrismi]

I need help to create images for my campaign (animations, frames, idle...) for fiery and glacial units (for both parts: shamans, ranged units, tank units, leaders, guardians, ... ).
if it's NOT possible, is there any fractions or campaign that contain such units that I can use freely?

[Shiki]

It is possible, but answering that part anyway

is there any fractions or campaign that contain such units that I can use freely?

Scroll through that list (it's very long though, >2000 units IIRC)
https://units.wesnoth.org/1.14/Ageless_ ... 20Era.html

Some might be:
the "Frozen" faction
the "Elementals" faction
"Summoners" faction has Elementals too
"The Warg" have flame spirits

From an add-on maintainer's perspective, it's best to not copy the WML files from the add-on, but to let this other add-on provide the units. That avoids the long-term issue of keeping the code up to date with Wesnoth's development.
