Make sure that there is not a folder within a folder, sometimes that can happen when you extract the files. What I am meaning is if you look in the HoodsButtons folder there may be another folder called HoodsButtons inside it that you have to open before you see the images.
If that is the case just copy the second folder, move back to the Bitmaps folder and paste, it will ask you if you want to overwrite just click OK.
Hope you understand what I am meaning.
