The image on the first post is already having the skin, so you just have to activate it once you have done the setup, on the setup menu you can select other skins (installed) than the default one.

The skin posted here I believe will work only on BH version, and not OpenPLi this due to differences in code/software between the OpenPLi and the BH based on OpenPLi that has various addons that OpenPLi is not capable of managing (that BH version does support).
