Say it's jQuery plugin

In readme and Github top desc. This is not LIGHTWEIGHT/ULTRAWEIGHT

Like this, for instance https://github.com/dbrekalo/simpleLightbox See here https://github.com/felixhagspiel/jsOnlyLightbox as well

Thanks

It's lightweight if you are already including jQuery or Mootools in your pages. Otherwise you can indeed find lighter solutions.
