Please use at least version 1.8.3 of NextGEN Gallery. This plugin is not tested with lower versions
NextGEN Gallery Comments give power to the best wordpress gallery plugin i have seen! With my plugin, now all users can leave comments to your galleries. Comments are also displayed in admin in Comments section and in manage gallery page.
** * * NOTE * * **
For now, comments are show on galleries only when they are not called directly in post/page with shortcode. Example:
[nggallery id=X] —-> gallery comments are not showed
[album id=X] —-> gallery comments are showed (Not in album list, but inside the gallery page)
I will check in next release to find a way to do it.
