My Pictures DB and Central MySql Database

I am using My Pictures DB and see that it can be set up to use a Central MySql Database to hopefully feed 3 x OSMC running on Raspeberry Pi(s). Can anyone please explain how?

I have a Synollogy NAS using MyPhp and Maria and this runs the database for Music and Videos for the 3 x OSMC machines. I was hoping that by adding to the advancedsettings.xml I would be able to include pictures from My Pictures DB but it doesn’t work. Listed below is the text from advancedsettings.xml – anyone any ideas…? Thanks
