I just started using NextGen and so far it seem great for my needs, big thanks to Alex Rabe for creating this!
After some confusion I've seem to have found some pages on the net listing the available shortcodes. But is there no official documentation of them, or did I just not find it?
What I'm wondering is if it's possible to list images with a certain tag, but only from a chosen gallery? Something like [nggtags gallery=blue id=2]
And even better if I could for example list all images tagged blue, but not the ones tagged house, and only from the album with id=2.
