Yes, that's quite possible and has happened few times that I am aware of. Of course, I don't use the maximum quality and resolution in any social media as my photos are available for sale as well with print quality and big sizes ;)
I use a tiny version of my logo, because generally I think big signatures and text distract the attention from the picture which isn't my goal ;)
Please do enjoy my visuals, @cicisaja, you're more than welcome :)))
