Image service
Google is warning me that I'm running out of photo storage space, so it's time to get serious about pulling my images out of Google photos and into some kind of useful local service.
The hard part, for me, at least, is designing a useful and plesent to use interface. I can lean on other designs, but it's still going to take a bit of work.
A specific feature I want is a 'Tag/Describe a random photo' page that loads a photo at random (either from all photos, or from untagged photos) and lets me set the tags and/or description. (Exif has an 'Image Description' field that's probably the right place to start).
