Hi!! Thank you so much, I'm really happy to hear that my little template has been helpful :D
I've also thought about whether it would be possible to make the tags shown in the lightbox function the same as the list of tags on the gallery view... I think it would take a bit of work with the javascript to make sure no weird side-effects come from the change, but it should be possible to make it work! Although it's not a feature I've looked into much, so it could either be simpler or more difficult than what I'm imagining ^^;
I'll keep it in mind for the next time I get to sit down and work on version 2.0 of the template :) (it might be a while yet, hah... busy life!)
