I made something for Mastodon: A gallery mini-app.
You can simply drop it in your Mastodon server's public folder, and it will show images from your server in a mosaic grid with infinite scroll. Supports some configuration as well, e.g. whether to limit it to only local images, or a specific hashtag, or which server to fetch from.
Using the Falkon browser, I only get a limited number of images. When I try it using MastaLab on my phone, I get a lot of images that don't show up on the browser version.
@Gargron You can code for Mastodon?? I mean... Could I if I wanted to? That's radical. I'm new to this social network and coding something for Twitter or Facebook would be just a dream. Is it possible to ADD things to the network?
Mastodon federates using the ActivityPub protocol, as does Pleroma, Peertube, plume, and pixelfed. Anyone with the appropriate skills can build their own social network that communicates with the rest of the fediverse using ActivityPub: https://www.w3.org/TR/activitypub/
You can also contribute code to mastodon itself through github: https://github.com/tootsuite/mastodon
The original server operated by the Mastodon gGmbH non-profit
