Quick steps:
- Use Vivaldi Browser.
- Set up a keyboard binding for taking pictures (you can screenshot and save it in the clipboard or save it to the folder).
- I save it to my local Dropbox folder.
- Download and install Google Photos sync and set up the same watch folder.
- Voila! Magic. By the time I am about to write, the pictures have automatically synced in the background. WordPress only links with Google Photos.
I prefer to automate my workflow. It helps to be efficient!
