Help..getting skin in map..

Ok..I know theres alot of these, but I've read every one of them..and none of htem help me. I edited the skin of a ogremagi and i've done everything and it's in .blp format, so now how do I put it in map, and get them to show in editor?

use WinMPQ and implant it into the map under the folder you found it in when it asks for it. ex:

\ReplaceableTextures

then go to the editor and put it there. if you save the map again, you gotta implant again.
