Newbie trying to apply a skin...

Hey I've searched for this and never found a straight answer so if someone who has done this before can help...I downloaded one of the skins from this sight which came in a folder with some jpegs and a resource.bin file. Do I just copy the resource.bin file into the root directory in order to update the skin? or do I need to copy the pictures as well? Thanks for helping out the new guy.

You only need to copy the resource.bin, any jpgs are only screenies to show you a sample of the skin.
One thing you need to be sure about however is using the appropriate firmware and skin versions. Different versions will not work togeather.
