Looks great.

I noticed from your domain you link to an old version for Prototype and Scriptaculous. The newer project page design is much cleaner and less distracting. It was hard for me to see the link to "A new (jQuery based) version of this script is available" from your old design. The yellow gets lost in the sea of colors below it. I almost commented on you not having a link, but I just couldn't find it.

Also, just wanted to point out a fatal error on your site:

    Fatal error: Maximum execution time of 5 seconds exceeded in C:\domains\nickstakenburg.com\subdomeinen\projects\library\Zend\Filter\PregReplace.php on line 25

Looks great.

Does it do inline pdf? I know that I had to hack fancybox to get pdf rendering to work properly (ie, loading the browser plugin within frame).

Very nice looking! I didn't look at the code, but am still going to say nice job. thanks for sharing with us.

what exactly are the differences between this and jquery lightbox?
