I decided to install BeforeDark on my Basilisk machine to install an old nostalgic desktop pattern. Unfortunately, it always did the "Aztec" wallpaper by layout.

Now I can't get rid of the Aztec design. It pops up every time I start up the Mac. The regular desktop pattern always shows, then the design launches. I can't get rid of it. I've deleted BeforeDark, I've switched the desktop pattern back to normal, I've trashed every desktop file [to rebuild it] I can find, I can't get rid of it. It comes up every time I start up.

Can anyone help?
