This allows you to create a fan page like button that has none of the fancy stuff normally that exists: stream, profile thumbnail, name. Button only.

Want to boost your Facebook fan page subscription rate? This plugin makes what should be an easy task, but isn't, an easy one. It enables you to use a shortcode to place a small like button where ever you like without the clutter: stream, faces, count, and all of the other junk that comes with the "fan page like box" ordinarily. Basically, it generates a fan page subscription button that looks identical to the one ordinarily only for sharing a page (as opposed to actually subscribing to the page).
