Please people, if you are looking for a gallery that will bring you traffic true search-engines. Don't install Nextgen Gallery. The way it is build will not deliver you any traffic. I'm working with different websites from 2004 till now, also using Yoast SEO for optimizing Nextgen on my latest website, but Google will not index the pictures correctly (even with tags, description and the titel filled in and the correct options)
I have asked for support (in this unordered topic) a while ago, but nobody responds.
After the last update all pictures also have the wrong date (1970) in stead of the correct meta date. The first user update request about this issue is from a month ago...
Developers, please do something about this. The base of the pluging is strong, but there are some major issues with the gallery
