Today I put the last things into imgup I need to just run it and use it. I cleaned up the result page, added a chance to enter alt text at the beginning, and made it clean up its tmp after it succeeds at uploading, which now has a cleaner error page for the most error-prone part of the app. I also have it using dotenv for configuration because that felt cleaner and more forward-looking than the YAML config thing.
There’s still a whole thing to do on the Smugmug side.
