Hey Alex, you should create URI's that display galleries based on tags.
For example, links could be of this format:
http://www.yourSite.com/Wordpress/ngg-tag/TagName
On my site for example, Maybe i want to show models of all my footwear that are called the "Rook"
the URL would be http://www.bettafootwear.com/ngg-tag/Rook
Users will see all shoes labeled "Rook" even if they are in different galleries. What do you think?
Also, would be cool to have multiple URI's that go to the same place.
Example:
bettafootwear.com/ngg-tag/Rook -----|
bettafootwear.com/footwear/Rook ----| All Same Page
bettafootwear.com/whatever/Rook ----|
All of these would load the same exact page and you can specify how many different URI names to have.
Would be awesome!
