I know this platform very well and I've used their free photos for one of my YouTube channel. This platform gives free stock photos but I did not know if you could get paid by uploading photos there.I have heard of Shutterstock, but I haven't visited their website before I don't know how much money they pay you for uploading your photos.
Just research around, maybe you will see where to sale it. But the pay maybe little though.
Before you upload any pics for sale just make sure the platform is legit and secure.
