Next Gen is not working

So I am not with Imagely, but I can tell you the format for my Tag codes, if it helps:

domain.com/pageorpost/nggallery/tags/tag

This is the same as what they told you basically for format.

However, I find it easiest to let NGG generate the tag links, rather than doing it myself. I a post called “test” (could have been a page just as easily) and inserted the gallery as a tag cloud (it has to be a gallery, it won’t take albums). Then I clicked on one of the pre-generated tags to see what opened:

polywogg.ca/test/nggallery/tags/Ottawa

This gave me the properly formatted link, with five components to the link:

a. Site: polywogg.ca
b. Post or page: test … just a temporary one, but you’ll need a permanent structure if you want to reuse all of them, otherwise the sublinks won’t work;
c. Control: nggallery to put you in the NGG control hierarchy for dynamically generated pages;
d. Category: tags to tell it that you’re sorting by tags
e. Tag: Ottawa in my case.

I wondered if it was your use of hyphens, but I have one:

http://polywogg.ca/test/nggallery/tags/panda-wedding

and it works just fine.

Just to confirm, are you sure your tag says “15-30” for each one i.e., not a range of tag 15 to tag 30 but an actual tag called “15-30”)…I also assume you’ve checked that you haven’t accidentally assigned all the tags to every photo?

Good luck!
