I'm not sure if anyone is aware of this, but there's Minecraft minifigure head decals in LEGO Digital Designer! Here are examples.
I discovered this when I uninstalled LDD and reinstalled it earlier today.
Unfortunately LEGO put a bugged version on their website.
Uninstall Lego Digital Designer
Delete this folder also (otherwise a reinstall will not work):
C:\Users\<YOUR USERNAME>\AppData\Roaming\LEGO Company\LEGO Digital Designer
Get this version https://web.archive.org/web/20190622153357/https://lc-www-live-s.legocdn.com/downloads/ldd2.0/installer/setupLDD-PC-4_3_11.exe
