If you own the webpage you are linking to, you can add [FB code] to the source of your webpage and you can edit the link on the fly via Publisher. For other links not owned by you, you can use our tool URL-shortener to create a short link. Copy the link you want to edit, paste it into URL-Shortener, and when we ask if you want to Edit it, click yes. Here you can edit the picture, the Title and Description.
