Despite Automatic Update being deselected, over night my wife's iMac decided to upgrade itself to 10.15.7. That then initiated a request to set-up ALL the iCloud details to match those within iCloud. Not so bad in itself until I got to the point where it gave the option for syncing photos and told me that if I did that 147MB would be copied over to iCloud.
At which point I bailed out and restored the original system. She has 17GB of photos !
