I currently run Gallery2 on my website and am looking to upgrade to Gallery3 when it is released.
I am trying to figure the main differences between Gallery3 and NextGen Gallery.
Apart from the obvious features of displaying my photos I want to
* Show maps with Geotagged photos on them
* Enable users to see similar photo based on the photo tag (keyword)
* Link a thumb nail in a post to a gallery/album (I know the 2 programs use those terms to mean exact opposites.)
Can anyone provide the similar pros and cons of each system.
