Using my version of Bulletproof and accompanying server code, I can now upload named images and put them into subdirectories of one of three different base directories.
This is basically so I can upload images with date-labeled human-readable filenames into topic-specific human-readable directories, using my phone.
This will come in super handy during my walk.
So far, I can upload the images, but not yet easily embed them into my Hugo website. (I embedded the above image with help from Firefox, BASH, ssh, and Emacs on my computer.)
