Well, I looked up your username on Codeberg and assumed https://codeberg.org/codewizard was you, so I thought you're a developer from the linked website.

Like what @pat_dev@social.linux.pizza said, sites like Codeberg and GitHub are intended to store code repositories, not photographs/albums and other personal files. If you were to host the source code of a website and have some images there that are part of the website, then sure, it's considered part of the website source.

I'd suggest looking for cloud drive/storage solutions (like we know it from Dropbox etc.) I've heard great things about Filen. They're based in Germany, end-to-end encrypted and their clients are open source. Or, of course, there's Nextcloud, but it either requires self-hosting skills or knowing someone who will host it for you (there are hosting providers out there).
