Is there a method to the madness here? A certain criteria? The reason I ask is because I have pictures that I know have been reposted (which is OK by the way) and yet this option never shows up on any of them either in mine or the other galleries they have been posted to. Same with miscellaneous photos that appear around the site. You know, the internet famous ones that are in everyone's "mix" galleries.
Any clarification on this? Thanks
