Deploying Wallpaper to an iPad or iPhone
Requirements
The iPad or iPhone must be supervised to receive wallpaper.
Image files must be a PNG or JPEG, and a maximum of 4MB.
For recommended dimensions for wallpaper deployment, see Tech Specs from Apple's support website.
Set the Home screen or Lock screen wallpaper on an iPad or iPhone with a Blueprint.
To prevent a user from changing the wallpaper, also select the "Prevent Changes to Wallpaper" restriction in the Blueprint.
Note:
You can also deploy wallpaper to a Mac using a Custom Profile. For more information, see Deploying Custom Profiles with Jamf Now
