most avatar textures ( skins, tattoos) aren't mod, creators mostly protect their work.

If your skin is mod, you mostly still won't have the skin textures. The owner does not give those out. So you only can mod it with the appearance tool.

The same with tattoos.

Tattoos are nearly never baked on the skin but additional layers.

You can add /change tattoos by simply buying or creating a new one, your skin doesn't have to change for that.
