The term Royale stands for "a custard cut into shapes and used as a garnish in soups."
Or it's French for the feminine version of Royal.
As you can see, way too much confusion can occur with this term.
RoyalStock.com is the best variation of these two words if you wanted to use "Royal" & "Stock" - but if your goal is to come across as Royalty Free Stock Photos... you might as well hand reg RFSPhotos.com
You can still get a refund if you delete the domain and contact support but heck you may as well hold it for the 1 year of registration to see if you get any offers.
Thank you very much for the input Perception. I just might hold onto it, see if I get any offers perhaps on AfterNic, Sedo, or Flippa. I don't know which is the best site to at least try to list it on for now.
