These files haven't been changed in the CVS in over 2 years.

It would save quite a bit of bandwidth if they were compressed and packed instead of used with comments and all.

I suggest leaving them uncompressed for easy modifications if they are needed and creating a duplicate called lightbox.pack.js and lightbox_lite.pack.js which are compressed and used on production sites. If not packed, then compress them and call them lightbox.min.js and lightbox_lite.min.js. This is how jQuery does it.
