I have a web page containing a number of images. Each image has a Facebook share button on it and a little description. What I want to do is, when the user clicks on the share button, the corresponding image and the description of that particular image is shared on Facebook.
I have been looking at Facebook's documentation, and what I understand so far is that Facebook takes the link of the page that you want to share and selects one image from it, that is displayed on the shared post.
Is there a way that I could specify the image's URL and the text of the description in the shared post?
