AWSPics

I use https://github.com/jpsim/AWSPics , which takes care of everything. It's great IF you're comfortable with your whole photo solution being cloud-based (but you still own and control it, you're not just handing it all off to a SaaS), rather than being self-hosted. Personally I prefer the former these days, but I know that I'm in the minority here on HN. With AWSPics, sync your photos (just a simple directory tree on your local device) to S3 (I just do it manually from time to time from my desktop, but no doubt it can be done automatically at regular intervals, and/or it can be done directly from a phone), then Lambda functions generate thumbnails and browsable galleries (as static HTML), then you can view it all via CloudFront (password-protected using Origin Access Identity). AWSPics isn't really being actively maintained these days.

I migrated my photo collection to https://github.com/jpsim/AWSPics about a year ago, pretty happy with it (so much so that I ended up contributing a number of features and bug fixes back to it). Basically all you have to do, after the initial setup, is an S3 sync to upload new photos, and a gallery web site and resized thumbnails get generated automatically. All private, you configure usernames and passwords. The ongoing cost is just that of S3 standard / infrequent-access storage, which for my collection of ~50GB is currently costing me about ~$1/month. In terms of the auto-generated gallery (lambda function that traverses an S3 bucket) and the password-protection (CloudFront Origin Access Identity), you're locked in to AWS. But in terms of the data, you by definition have all the files in a simple folder tree on your local disk too, you
