Well i made the .tga, converted to .blp...now what?

i made an awesome reskin of an arthas model and just finished converting it to .blp using warcraft 3 viewer....but now what? i want to attach it to the model and see what it looks like......how in the monkey do i do that? emote_confused

Click here for a step-by-step tutorial on how to do it.

arthas's path is always a b.i.t.c.h, its textures\arthas.blp
ppl usually put units\human\arthas\arthas.blp which is wrong
