True.* for the content. Gallery layouts are of course really powerful, maybe even to the point of offering too much configuration options to be intuitive for new users.
Unfortunately, I don't think this is possible, or at best too complicated. IPTC data is created from a file app/asset-types/image.inc.php, but then we use templates like https://github.com/mjau-mjau/x3/blob/master/app/twig/partials/module.gallery.html to render these stored values, and the templates are pre-rendered into unreadable app/templates.I just wonder if there might be a way to "manipulate" Photo.Gallery X3, so that additional IPTC can be displayed
Indeed Files Gallery is much more flexible in terms of IPTC, and X4 would definitely take a lot of inspiration from Files Gallery.as this seems to work perfectly in Files Gallery.
Yes, we can of course support additional IPTC values. Thanks for noting.Moreover, can you add reading more IPTC fields from JPG, that Lightroom fills using reverse geocoding feature, like "Country", "Province", "City" and so on... Would like to use these in EXIF, Thanks!
