Couldn't you also embed data into images and upload them to Google photos, or is that discarded when they convert and compress the image in the backend?

Depends how you encode it. A bunch QR codes, no problem. But encoding into the individual pixel, probably not so much.

I mean include binary data in an image file. So you would have a 300x300px jpg picture of a flower that's 20mb which you could unpack to a binary file.

storing original photo will use google drive space quota (if you don't have a pixel phone).

only high quality is unlimited (reduced size)

so, if your data survive photo compression technology, you can do it.

Check the issues! Some people have tried quite hard to figure that one out.
