Change initial LOG IN background on Macbook M4

With reference to changing to initial LOG IN screen on macbook air m4, I have turned off File Vault, and set 'When Switching User to: 'Log in shows list of users'. How do I change the lockscreen.png photo to one that I have saved on my desktop please?

MacBook Air 15″, macOS 26.6
