50mm is a Go based photo gallery web application that I created when I couldn’t find anything that fit my requirements.
I needed a fast, Amazon S3 backed (so no database involved), photo gallery generator, that also used the Imgix image processing service for real-time resizing of the images before displaying them.
In short, I wanted to be able to be able to upload my full size images onto S3, and not worry about resizing them or wait for them to be synced with a database or similar. I wanted a seamless experience:
Upload files -> see them on the site
50mm is now powering my own photo gallery, as well as a few others that I know of.
