OneDrive syncing

Hello, 

Please could someone assist me in trying to figure out how to stop onedrive sycning gallery photos and ingame photos?!

I have random gallery photos saving automatically even though I haven't used the gallery recently. Also all of the in game photos I take save automatically. Everytime i play sims I have to sit and delete 300+ photos! 

I did initially turn off the document folder back up but then realised this stopped my whole game being backed up and lost all of my current games...got them back once I turned it back on thankfully!

I need to keep onedrive synced to the pc as I use it for work and I would like to keep sims backed up, is it possible to turn off just syncing of all photos?

Please help, as if I can't get this figured out I'm going to have to stop playing 😫
