Showcase – WordPress Gallery Plugin
o the default WordPress gallery sucks. It’s not very powerful or flexible. It just spits out your images. But you don’t want that, you want fancy lightbox slideshows and drag and drop ordering and all kinds of bells and whistles.
That’s where Showcase comes in. Showcase aims to redefine the “gallery” in WordPress. Showcase makes the whole process of uploading, ordering and editing your images as simple as it can be. Then it makes your gallery look stunning by automatically showing your gallery in a beautiful lightbox slideshow.
