 * Hi,
 * I’m running version 1.3.2 of NGG and I’ve ran into 2 “minor” problems.
 * The first, and probably the most important one, is the duplicated content problem
   generated when having galleries with 2 or more pages (paginated) displayed in
   your blog.
 * Since the plugin prints a built-in navigation index (page 1 2 3 … [10]) it produces
   different gallery pages but the same post text for each page, so when visiting
   googles webmaster’s tools, you can check how many pages are tagged as “duplicated
   content” only because those posts/pages have multipage galleries:
 * [http://www.grabup.com/uploads/7900225006BA20095D202056BE45.png](http://www.grabup.com/uploads/7900225006BA20095D202056BE45.png)
 * In this case, the post has ../page-4/ and ../page-9/ as trailing url because 
   those are actually page 4 and 9 of that particular post’s gallery and off course
   tagged as duplicated by google.
 * An easy fix could be just adding ‘rel=”nofollow”‘ to the page index links under
   plugins/nextgen-gallery/lib/core.php lines 163,176 and 188, but probably someone
   could come up with something more interesting for it.
 * —
 * The second minor error I wanted to point out it’s about HTML validation. There
   is a small error in the galley page number wich prints the css ID=”ngg-next-{
   page-id}”, for example “ngg-next-2”.
 * Since you can have more than one multipage gallery in the same post, the ngg-
   next-2 ID could be duplicated and therfore invalid since you can only use the
   same id once in CSS.
 * id=”ngg-next-‘ . $args[‘nggpage’] . ‘”
 * Well, thank you very much for such a great work with this plugin!
    Cheers. Pepe.-
