We're currently using version 4.4.2 of the nanoGALLERY library, if you come across any issues with it you can report them on the project Github page at https://github.com/Kris-B/nanoGALLERY
We're making use of the cdnjs.com CDN to provide the nanoGALLERY library http://cdnjs.com/libraries/nanogallery. They don't seem to list the current version (4.4.2) on their frontend but it is available on the CDN and the author does publish a direct link to cdnjs.com on their website.
