I'm a fan, makes it super easy to go on vacation with family, suck in all the photos from 5 cameras, and tag them all. It's particularly good at things like select 2 weeks of photos, tag them with the vacation location, then pick ranges to tag bears, rainbows, avalanches, people, flowers, waterfalls, etc.

Granted I suspect 90% of my tag usage is grand parents finding all the grand kid photos. It works really well with piwigo mentioned on another thread.

Fan, too. Had some stability problems two years ago, now it's smooth. Having access to quickly shown thumbnails is yes or now for actually accessing photos/images and enjoying watching them and working with them.

I didn't try option to write to metadata for compatibility.

Will have a look at piwigo.

I use DigiKam as well, under Windows 10. Recently the facial recognition has gotten better, and it's far less crashy than it used to be. I've got about 400,000 photos taking 650 Gigabytes.

I have 125k images and 57k photos totaling 280GB and it's smooth. I switched to desktop recently which definitely adds some points.
