BUG一大堆，而作者又開發了PRO的付費版，整個 2.X 版本後給他擺爛！
Recently been looking for an easy to use plugin of WP album, I found the name call ” NextGen gallery”,
However, since the update to 2.0 or more, screams everywhere, whether in education is not enough,
the word will disappear defined CSS styles,
SO many bug in this version, and the author developed after paying PRO version 2.x version of the overall conversion,
his would not debug for 2.x free version.
Therefore, we recommend that you install the most stable 1.9.13 version of the classic!
