First of all- great work and thank you for sharing!
I'm using jQuery Lightbox with plugin for flickr stream and as soon I'm done with my site I will show you the result.
There is one think, that can make the script even better: I was looking in the script's files for a place to add social share links. I think in the light box next to the title will be good place for facebook, google+ and twitter share links.
What you think about this?
Do you think you will have the time adding this function?
Or you can give a hint where in the script to look?
Thank you and all best :)
