Is there a way to have one's own gallery thumbnails available when sharing gallery images on Facebook? I used to be able to do that after uploading something new to my gallery (which I admit, has been a while), but when I tried to do that today with a new image I added to my gallery, the only thumbnails available for selection when I go to post it on FB are of other people's work - the stuff that appears in the header of the pages at CGS, I guess.
I'd really like to use my own thumbnail when I share my work on FB, is this not possible any longer? Or am I doing something wrong?
Thanks so much. :)
