Displaying a Custom Picture on a Locked Screen
You can display a picture of your choice on the client screen while it is locked by Apple
Remote Desktop. When creating images, make sure the image size will fit on the client
computer’s screen. For example, if you have clients with 800 x 600 screens, a picture
that is 1024 x 768 will be scaled down to fit the screen.
To create a custom locked screen picture:
Create a picture using a graphics program, such as AppleWorks.
Save the picture in PICT, TIFF, GIF, JPEG, or any other QuickTime-compatible static image
QuickTime-compatible movies or QuickTime VR objects cannot be used.
Name the picture “Lock Screen Picture”.
Copy the “Lock Screen Picture” file to /Library/Preferences/ on the client computer.
