Rather than make the download directly available here, you can always obtain the latest official version of ExhibitPlus from the skin section of the JAlbum website. Remember that ExhibitPlus almost always comes bundled with each JAlbum version, so unless there has been a minor update, there is usually no need to download the skin separately.
You can jump directly to the download link here.
Latest release version: 1.5 (01 April 2007)
Bundled with JAlbum version: 7.2 and all subsequent versions
