It's very easy. You just don't tranmit images of another person without their permission.
Just don't do it. Ever.
And even easier is to never give permission. It's rarely the first layer of permission you have to worry about, it's the scum under that layer.
In case people have missed the last 20 years, you even need permission and approval in many situations where people actually have their clothes on to take photos. Not sure why so many struggle understanding naked ones need a whole extra layer of approvals. It's not just harmless fun but can lead to a lifetime of depression or suicide.
Just don't do it. Ever.
