Whenever I post the link to my site on facebook it displays a default image that I used to use for this purpose. But I did the image change in the TAG below for more than 6 days, only the old one still appears. Remembering that the new image has a new name and the old one was deleted from the server, but I still do not know where to capture the old one.
Already testing on multiple computers and mobile devices.
