where are the original backgrounds for development ?

i wonder where i can change the original backgrounds

normal the backgrounds are always here...

/usr/share/backgrounds (but the backgrounds that chaletos started wet are not there)

/usr/share/xfce4/backdrops/ not here

i want to change the start up background for development like in ubuntu 14.04

nobody know's this , normal in any ubuntu ,if you wanna use your wallpapers to startup your wallpapers ,you must not rename the original wallpapers ever.
you must overwhrite the wallpapers in /usr/share/background this is where the wallpaers must be , but where are the original wallpapers for chaletos?

not in backdrop , not in xfce can not tested to the full
