I hesitate to ask this but... Does anyone have or know about code that can write metadata directly into Google Photos. In essence what I have in mind is this: having got Google Photos AI to select a category of photos, say 'tennis' I'd like to be able to 'tag' all those images in the appropriate metadata field. What I don't really wish to do is down-load the selected images, apply the metadata locally then upload them all back again. Especially if there is maybe 50,000 images to work through.
