F14 - Changing GDM Background

[Sawrub]

  Hello All,

Setting default GDM background was a little easy till F12 by using the 
'Set as Default' button, but i can't see it there now in F14. Please 
rescue me to change it.
Is there any way to set the same for the playmouth, so as to have one 
background right from the time when booting starts.
