Gallery lets me host and view any collection(s) of images. See the description for the repository.

A simple web-app I use to help me do a few things:

• Host my many desktop backgrounds outside of my .files repository, so it doesn't get huge with hundreds of high-resolution images. This is hosted on a droplet.
• Run the server locally to serve all of my screenshots that I've taken. Doing this lets me find an old screenshot by image, instead of its filename, which only gives timestamp information.
• As a dependency for my bookshelf project; Gallery helps display my to-read bookshelf via their covers, so that I can identify them visually instead of just by their titles.

There are some things I didn't bother to do because I personally didn't care for them too much. Some of them are things I will care about eventually and will do, others likely never.

• Gallery does not support nested directory structures. It will ignore nested directories and not walk them recursively looking for images.
• Non-image files are not detected or ignored, so they show up with a broken image icon. Kind of ugly, but all my use-cases never run into this so I don't really care.
