Testing out Pixelfed. Could this be a good tool for sharing art assets?

I've been talking with folks about what might be the best tools for sharing photos for use when running games. In addition to maps, I enjoy showing players art and photos as backgrounds. We usually play on Roll20 virtual tabletop, and it acts like a little dollhouse or stage background.

Here are four photos I took outside the California Academy of Sciences, which is a museum in San Francisco with pretty solarpunk architecture. Does this seem like a useful way to collect up visual assets and make them easy for folks to find?
