Ask HN: What is the best JavaScript gallery to use for these purposes?

I'm looking for the best javascript gallery out there that fits these needs:

1) Can be used in an iframe

2) Can support both photo and videos in the gallery

3) UI/styles can be customized

4) Works properly on mobile devices

Right now http://photoswipe.com/ has the lead, but you have to hack it for it to work with videos, and also for it to work right on mobile and inside of an iframe. Wondering if there are any better alternatives that I'm missing.
