I was unable to find discussion of this specific problem... I'll do my best to explain it, but I think there is a loop issue where tags are being called before the sorting command.
My site has different galleries. When a user clicks a gallery, the gallery pulls the photos tag, so the same photos can end up in different galleries.
(e.g. I have a gallery called "Mountain Pics" and one called "Lake Pics." I have three photos: 1) a mountain photo tagged "mount", 2) a lake photo tagged "lake", and 3) a photo of a mountain with a lake in the foreground tagged "mount, lake". So photo 3 ends up being displayed in both galleries.)
The photos are kept in one main gallery. The other galleries (i.e. "Mountain Pics" and "Lake Pics" don't actually contain any photos, but call out the tags from the main gallery using:
[nggtags gallery=mount]
I need the galleries to show the most recent photos first, but the sorting (I've tried them all) won't translate to the website. The gallery will reorder in "manage gallery", but when I open the gallery on the website, the order won't change. This ONLY happens with tags. If I call the photos out with
[nggallery id=10]
the gallery sorting works as it should.
Things I have tried without success:
1) Under "Gallery" -> "Options" -> "Gallery" I've tried all the different "sort thumbs" options, and both "sort directions". Though the gallery will change order under "manage gallery" it won't translate to the website.
2) I've tried "custom order" in the "manage gallery" and same thing, the "manage gallery" will change order, but won't translate to the website.
3) I've tried deactivating all plugins except for Nexgen, and difference.
4) I'm updated on WordPress and Nexgen (1.6.2)
