I’ve searched through the Wordpress plugins and there is nothing like this, but I think it would be great to be able to connect a Wordpress blog (self-hosted or not) to a Nextcloud server.
I mean something like https://wordpress.org/plugins/cbxdropboxfilechooser, which supposedly enables inserting files from that cloud in your blog.
My use case is this: I have a blog hosted in a shared server, and I had not too much disk space. Whenever I wanted to insert an image, I had to upload there. But, as I have a home Nextcloud server, I’d like to use the files directly from within it, as it would save me a lot of disk space in the hosting.
It would one of those little things that help spreading the word.
