Looking at the Imagebriefs postings, there doesn't seem to be a consistent way of posting. They all reference "Permitted Uses" which is how they intend to use the image, and then under Exclusivity almost all say "not exclusive". Am I ok to submit for ones that don't indicate Royalty Free under permitted uses? In other words, if they say the permitted use is "Broadcast", or "Book Cover" or "Print Editorial" (essentially not including the words Royalty Free) is that just a more specific way of saying Rights Managed?
