DMG background image not visible on old macOS

I distribute my AppleScript applet in a read only DMG file. I want to add a simple background image which encourages users to copy the applet to their Applications folder. I use the Finder function "Show View Options" which has the option to add a picture.

That seems to work in macOS Tahoe. However, the background image is not visible on earlier versions of macOS.

I've also found that a background image set on a Mac running Monterey is not visible on a Mac running Tahoe.

Is there a way to add a background image which works across multiple macOS versions ?
