Adding a edited .BLP

[Jimbo13]

I am trying to do some texture edits they are going in to a Copy client and only being viewed in Wow model viewer.

I have Keeshans Bandana on my toon I extracted the texture in Wow model viewer, edited and converted back to Helm_Blindfold_A_01Red.BLP.

Now how do I figure out which .mpq the original is in to replace it in Warcraft Studio?

Thanks.
