For questions regarding the Phoca gallery software you probably better ask in a Phoca forum..

Anyway,

my Fotos are titeld and keyworded and geotaged with Adobe lightroom, it is not possible to learn it when adding to a Category?

if I understood correctly you want title, keywords and geotag extracted automatically while uploading? Then your software has to write them into standard fields of the image. Taking for example the image https://www.kocher.photos/piwigo/pictur … tegory/103 there are only two IPTC fields 2#055 (DateCreated) = 20120103 and 2#090 (City) = Istanbul, there is no title and no geotag, not even in XMP fields. If that image is not a good example you may try another one by copying it to sample.jpg and execute [b]php -f piwigo/tools/metadata.php[/p] or if you don't have shell access copy the image to piwigo/tools/sample.jpg and browse to https://www.kocher.photos/piwigo/tools/metadata.php (both methods don't show XMP fields though).

For Piwigo's metadata handling see https://piwigo.org/doc/doku.php?id=user … n:metadata

Note that to extract IPTC fields as keywords some local config with the mapping needs to be set up, see also https://piwigo.org/forum/viewtopic.php? … 81#p166781 and https://piwigo.org/forum/viewtopic.php? … 81#p168381

To extract XMP keywords (if your software writes them) you'd have to create a plugin and add an entry to the $conf['use_exif_mapping'] array, see https://piwigo.org/forum/viewtopic.php?id=25709

There are some threads about geotagging in the forum, use Search.
