Quick question:
Do you think the people/curators that visit your post know if the image you used is free or not if you do not mention it anywhere?
It would take you 5 seconds to paste the link to the source and everyone else could quickly check where the photo comes from. It would not only save curators and other users time to look for the image each time, but also would make your post look more honest.
