Find the skin in WC3viewer you want to change. Export the current file (blp) as a .TGA file. Make sure it's 32 bit. Open the TGA file in Photoshop. Skin. Save. Go back in WC3Viewer, change your custom TGA file in a BLP. 32 bit. Import in worldeditor. Change the path of your custom file to the path of the skin that you want to replace. Save map. Close worldeditor. Open worldeditor. Open map.
If you cannot open/save TGA files properly, you need the TGA plug-in. Download it from adobe's site.

But how to skin? I mean how to replace textures from one skin (death knight) to another (footman)? And how to know about custom path?
OMG, that is NOT skinning. Thats the ass ugly CnP that sux ass. Skinning is clearing ur surface, doing ur basic colour, shading, doing the details, shade them and BOOM! u got a freehand skin.
It only has the RoC skins because you, GASP, only opened the RoC mpq file! Its not a magical program that can open two mpq files at once you know, open the TFT mpq to use TFT skins and models
