I installed the package, then wondered, what next? WWW <https://www.kde.org/> is not wallpaper-oriented. Is there a better URL? Via FreshPorts, <https://github.com/freebsd/freebsd-ports/blob/main/x11-themes/wallpapers-freebsd-kde/pkg-plist> there's a list of files, however the .js file was a mystery.
(In reply to Graham Perrin from comment #0) Right-click on the desktop, choose "Configure Desktop and Wallpaper" and look for "Stripes: FreeBSD" wallpapers. They were created for FreeBSD back in KDE SC 4 times: https://cukic.co/2010/08/12/distribution-branding-and-stripes/ I'm not sure what would you like in the package message.
