Course image thumbnail for Facebook posts
Hi all! Does anyone know what sort of voodoo magic you have to do in order to make Facebook automatically pull in a a thumbnail image from your course files when you post the link to Facebook? (I know you can add an image to the post as a separate step, but I'm not crazy about that because when users click on that image it just opens up the larger version of the image, rather than link them to the course.) I've googled a bit on this and am not coming up with anything.
