/*
Popupwindow plugin for jQuery.
by: Tony Petruzzi
homepage: http://rip747.wordpress.com
plugin download: http://rip747.wordpress.com/2007/03/02/the-return-of-popupwindow-jquery-plugin/
  
Takes a link and will create a popupwindow based on the href of the link. You can
over ride the default setting by passing your own settings using the REL attribute
of the link. You can have different setting for each link if you'd like.
   
To use just include the plugin in the HEAD section of the page AFTER calling jQuery.
After that, use jQuery to find the links you want and pass any parameters you want

04/04/2007:

1) added profiles so you don't have to pass the settings for each link anymore.
2) remove resize as a setting and add the correct setting resizable
3) removed example text from this file and made an index.htm files to house example.
4) add example of using profiles to the new examples page.
5) example pulls the latest jquery library from jquery.com.

05/14/2007

1) removed trailing comma in settings that was causing IE to bottom out with an error.
