I use your plugin on Wordpress with the "wp_enqueue_script", but this function adds an "?ver=1.0" to the end of the url, making the "baseurl" calculation fail; I propose a change from:

this.baseurl = $('script[src$='+this.files.js.lightbox+']').attr('src');
this.baseurl = this.baseurl.substring(0, this.baseurl.length-this.files.js.lightbox.length);

to:

this.baseurl = $('script[src*='+this.files.js.lightbox+']').attr('src');
this.baseurl = this.baseurl.substring(0, this.baseurl.indexOf(this.files.js.lightbox));

This seems to work better when there are request parameters passed to the ".js" file!
