Friends,

Our nonprofit has about 20,000 photos taken over 25 years in as many countries.

The photos are stored in a folder tree that has a sub-folder for every country and, under these, sub-folders for cities, universities, and hospitals (some of the folder names indicating which year the photos were taken, like...

Photos/Nigeria/Abuja2008

or

Photos/PapauNewGuinea/EducationDepartment

Many of the older photos lack GPS info, so I'd like, as much as possible, to retain the folder names as keywords in the Piwigo database.

Any advice on how to accomplish this?
