Feel free to do what ever you like with it. ;)

@aurelienpierre should know all the other answers, I have no wp and no experience with it. The script is just a blindly hacked skeleton

At least Windows 10 has curl in his path too, I just checkt on a fresh installation:

Do we want to save the images locally or just send them to wordpress? If we take control of the export, then darktable defaults to exporting the images to config.tmp_dir. We can just take them one by one (or maybe as a batch) and send them to wordpress, then delete them after we are done.
I will go as far as comparing control sums on distant server and local client, so maybe using a temp dir and deleting it once upload is complete and verified sounds like the best way.
We'll need to get logon and password. Do we store them, or ask each time?
WP stores a cookie, when using Rest API. I need to check what its lifespan is. Bottom line is, as long as the cookie is active, you don't need to login again. Otherwise, we can store in using the same libsecret or kwallet or whatever.
A thought about the export directory. Do we want to save the images locally or just send them to wordpress?

macOS and linux have curl in the path. Windows needs curl.exe. You could use df.get_executable_path_widget({curl}) and it will provide the file selector widget for windows and store the result in a preference that df.check_if_bin_exists() looks for.
This may be a script that needs a lib dir. I'm thinking about putting all the rest stuff in a library. Thoughts?
If you would like, go ahead and start a repository with this, and I'll fork it and do PR's.
