igohigh, those .pngs are what Pro-Pack and P5 use instead of the .rsr files, they aren't textures. I personally think merchants should just provide the .rsr files, it makes for slightly smaller downloads too, as Pro-Pack and P5 make their own .png files from them anyway. According to the readme for the product (which I just read in the Marketplace) the textures are in *RuntimeTexturesBVH TEXTURES where * is your Poser.
