Hi guys,
i've search into the forum but i've not find a solution, so i've decided to open a new topic. What i'm looking for is a way to organize the tags, i mean, i'd like to have categories tags that can help me out to put each tag in his category.
Example:

TAGS: apple, potatoes, tomatos, melon, bananas...

CATEGORY: fruit, meat, vegetables and so on..

I'm asking you if someone can help me to associate the tags to the category like a tree structure and to get category into father category..

Hope someone of you gentlemen could have a min to figure it out..

Zenphoto does not have categories in that sense. If anything the albums would be categories. You can assign tags to an album and get them via the class method http://www.zenphoto.org/documentation/classes/Album.html#methodgetTags.
