Desktop wallpaper and lockscreen

[saniyadav]

Hello All, Can someone please guide me on this? I have two images one that I want to set as the wallpaper and the other as the lock screen. What are the possible ways to achieve this?

Generally speaking, no. Apples Lock Screen image is protected by System Integrity Protection. If SIP is disabled you could replace the image file, but it will revert with each OS update. Disabling SIP is a very stupid thing to do, and must be done locally on the device, it cannot be scripted or performed remotely. 

Some tools like Jamf Connect run as applications on top of the MacOS Login Window, these applications can have their own images and is the only real way to do what you are wanting.

I send an image file to all of my Macs for the desktop background, I put it in a location that can be accessed for read by everyone.
I then use Jamf in a Restrictions configuration profile to point to and lock the desktop background. Once an account has logged in and the background has been set, I find the Login screen background will set itself to be the same background. However the Lock screen background never changes.

I am thinking my Login screen one is because I have it set in Jamf connect, its been a while since I last checked all of the settings in there.
I do not think it is possible to change the Lock screen one in any safe way.
