The end credits for "Shared Planet", tt32314942, have archive credits for items purchased from companies on another company's storefront. For instance: Items from The Bettmann Archives purchased on the Getty Images storefront (Credited as Getty Images/Bettmann). Another instance is AerialScapes images purchased from the Pond5 storefront (Credited as Pond5/AerialScapes). HOW DO I ENTER THESE CREDITS?
