I haven't touched the UI since then, its ugly but it works, I've tried allocating time to make more modern version and even started refactoring it a few times with a few friends in our spare time, but unfortunately finding time next to full-time jobs and family is much harder than it was 10+ years ago :)
I've never advertised it anywhere except shared with friends and used it on some forums in the past, but it slowly grew to 10k registered members and almost 200k uploaded pictures. At this scale (~100GB of data) its very cheap to keep it online since its using very small amount of resources on dedicated servers where I host some other important apps with regular off-site backups, but if it ever spikes and becomes problematic financially it will at least give me more motivation to make something more serious out of it or just slam ads onto it and call it a day (worst case scenario, not a fan of it).
