Being new to all this, just installed nextcloud via my unraid docker, is this something that will work on my system? How exactly do I install this? Total nubie here.
Log in as your Nextcloud administrator and select Apps from the menu that pops up when you click your profile image/symbol in the top right corner.
The Photo app is among all the apps - it’s most likely already installed, but you may have to activate it.
Then click the photo app icon in your top left menu/toolbar.
That should be it.
If it looks good to you, then you’re good to go.
And if you want to check out the old Gallery app, just follow the instructions in this post.
The old and the new apps can co-exist.
Welcome to Nextcloud 
Quick follow up question. Is there a way to sort the photos by filename in the current photos app? I don’t see any sorting options. Perhaps editing of a file to set sort? My files are named by date and even though in a browser on my drive, they sort properly, in nextcloud they do not.
Hehe, welcome to the frustrated crowd.
I recommend you check out the old Gallery app, and see if that doesn’t suit you better?
It can sort by name and date, and essentially for me; it can show pictures from external storage.
The instructions in the post I linked to worked fine for me.
I really with they would have invested their efforts into improving the old Gallery app and added features to that, instead of starting from scratch with the new Photos app 
Hello guys.
I’ve got question. One of the thing i love about google photos, is that i may create album, and choose what photos i may put there. So there is ALBUM NAME with photos (from many directories where i uploaded them) that i choose.
Is there any way of doing that with Photos app or Gallery app?
I saw “Albums” in Photos app (NC19), but those are just directories with photos inside. I would like to make an Album (not directory!), and choose what photos should be inside, and then share such album with family. Is it possible with NC?
I think you need a sharing function through the nextcloud tagging feature. I think it does not exist.

Hi there,
one question: how can I change how photos in album view are sorted?
When I share a album via link, there are dropdown at the top to change sorting (I want alphabetical descending), but when I am logged in, the browser-view does not have that. It seems to be sorted alphabetical reverse, I need it the other way round.
Thanks in advance
Sorry no idea. But i think that is not a photo album but a file sorting feature.
No, in the file view (/index.php/apps/files/) I can sort however I like. As I can in a shared folder (/index.php/s/), but not in an album view (/index.php/apps/photos/albums) in photo app. That problem is exclusive to photo app album view from inside the web-backend as far as I can tell…
I think the problem is that it uses remote.php/dav (that is ugly). Why does it use WebDAV features?
I just tested this “hack” in nextcloud 19, it doesnt work. It seems it does not get the correct url for the webdav to show the previews.
Do i need to do anything after fetching the updated purify script ? maybe rebuild js or something similar ?
Tonny. I just tried it in NC19 and it worked for me. I’m running NC19.0.1 in a LinuxServer Docker container.
I am not sure what to say, but it simply doesn’t work with the following factors/parameters
nextcloud 18.0.4
external storage: s3
thousands of files
browsing “your albums”
Everything is slow, clicking on a photo only after many seconds tries to open the black “large” canvas on which you’d expect the photo, but the webserver is so overwhelmed that the Kubernetes liveness and readiness probes kick in.
This thing really needs to temper it’s server resource usage
just increased NC max-version in the quickfix
-> NC 19.0.1 with old gallery app 
I agree. I haven’t used the app much, but it is anyway practically not usable. I have e.g. tried to figure out how to add new albums and had no success. I just sit there and see the photos and can’t share them with others, because they are all there in one album/folder.
Right click doesn’t help, I get only the browser’s context menu. There is no circled “+” anywhere, and no menu indicator. It’s claimed to be a fantastic tool, I’m yet to figure out how this becomes usable.
So updated howto:
/apps/gallery/js/vendor/dompurify/src/purify.js
has to be replaced by
https://raw.githubusercontent.com/cure53/DOMPurify/1.0.11/dist/purify.js
And
/var/www/nextcloud/apps/gallery/appinfo/info.xml
bump that max-version to 666 or something suitable
and then
sudo -u www-data php /var/www/nextcloud/occ app:enable gallery
Seeing as the gallery app is no longer maintained… who is handling security issues for it?
Might be a good idea to stick with the photos app for that reason alone.
This might be done via - photos tagged with a keyword (album name) might be grouped together.
Thank You. I will try that.
EDIT: ok i added tag to few photos, but i can’t find way to share that. How can i do that?
Also, is there any way to add many photos by selecting them for example? I also didn’t find it possible.
Hi Georg-Git, where would the Nextcloud root directory be in an Snap installation on Ubuntu 18.04?
