No. All instances I've tried over the years have been dead or full or not accepting new users otherwise.
Since Flickr was killed, I've been hoping to find a working photo community or even just some gallery space. Or even a static generator I could use. Haven't found anything usable.
pixelfed.social and metapixl.com both have active communities and open signups right now. Main reason to use metapixl.com afaik is larger file sizes are allowed (26mb vs 15mb)
edit: and you can upload 20 images to a collection on metapixl.com, instead of only 10 on pixelfed.social
also metapixl.com is based in Finland, and has some specific rules regarding content illegal in Germany etc, so they probably drop ban hammers on certain groups of abusive people harder than other servers might.
however, found the main trade-off is that pixelfed.social gives you 7GB of storage, while metapixl.com gives you only 4GB.
but be aware that some details are outdated, and you won’t know the actual file sizes allowed, number of photos in a collection, etc, until you’re on that server’s main page under the “About” tab. For instance metapixl is listed there as allowing 50 photos per collection, but that was downgraded to only 20.
