I would say it is, but to be fair, i work as a programmer and with Linux on a daily basis.
But there are plenty of tutorials which teach you to flash some OS to your Pi or even complete guides to build immich on top of a pi:( https://pimylifeup.com/raspberry-pi-immich/ )
The raspberry pi is the famoust single board Computer and therefore there are tons of projects and things you can do with it.
Immich is the best alternative I can think of. It runs about 2 years now on my raspberry pi.
And there is even a OpenSource Companion App which syncs Photos Automatically to the Server (https://droidify.eu.org/app/?id=app.alextran.immich&repo_address=https%3A%2F%2Ff-droid.org%2Frepo .
The Search is so good that I host another sever just for my meme-Collection! It even recognise Tags like NSFW out of the Box. And all that on your own hardware! You can search by people, cities, countries Dates, Devices and so on
You can selhost it on your own Hardware. Its pretty simple. You just have to install docker and docker-compose and follow the instructions on their site.
If you followed and learned that, you can pretty much host ANY other App just like that. Its pretty much always the same steps.
In my experience shit just works in Linux. I own an 10+ year old external DVD-Drive and an newer external BD-Diskdrive. And both of em work flawless on Manjaro.
Thank you! Gone are the days were I said “Wait! I have a meme for that!” -> Since Immich it is just “Here is a meme for that!”
