/*
    Popcorn version 1.0 - © Copyright 2009 by Isotop AB
    Info: Popcorn is an expanded version of Thickbox. 
    Author: Björn Lennartsson



    ::: Usage :::

    a. To load a image popup gallery (if you do not wan't a gallery you just remove the rel-attribute)
    1. <a href="SOURCE_TO_BIG_IMAGE" class="popcorn" rel="gallery"><img src="THUMB" /></a>
    2. FINISHED!

    b. To load Iframed content
    1. <a href="SOURCE_URL?TB_iframe=true&KeepAlive=true&width=XXX&height=YYY" class="popcorn">IFRAME POP</a>
    2. Erhh, FINISHED!

    c. To load a specific div, any possible who is located on the current page.
    1. On the element that is supposed to pop it, put following: onclick="Popcorn.Pop('DIVS ID/CLASS', null, null);return false;"
    2. You will need to have a button in the div so you can close the overlay, add following: onclick="Popcorn.Close();return false;"
    3. The div should have it's style attribute with display:none, THIS IS IMPORTANT!
