Just installed NextGEN and generated a gallery. It doesn't look anything like the demo site one. Changing the css style to some of the other ones doesn't seem to do anything other than change the thumbnail borders.
Can someone tell me what the "style" of the demo site is? I'm talking mainly about the thickbox/lightbox styling of the images once clicked on, but also how close and organized the thumbnails are. It looks way different on my site.
My site also has a weird orange highlight one mouseover of thumbs, but the demo site doesn't have anything like that.
Here's where I'm using it: http://louiselfman.com/portfolio/buzzine/
