@Mayana At least for me, sometimes I click a picture to find out more about it. But when I’ve asked around on other platforms in the past very few are interested in the caption (in fact, the less I enter the more likely the image is to go viral — which is weird!) and the caption takes time to enter. Putting the website at least gives a bit of context and makes it harder for large companies to say “Oh, I didn’t know that image wasn’t free to use on our corporate homepage!”
