The detective in me thinks that: (a) The package in her hands that looks like flowers could be something given to welcome her; but (b) she looks as if she's ready to go up the stairs to the plane and has turned back (maybe to allow this picture to be taken).
So (c), I don't know if she's coming or going, LOL. So much for my detective work.
On reflection, I think maybe Susan is leaving France.
Thinking back to the video you had linked to the site Ginger, I seem to remember her arriving in daylight. This picture looks like evening. Oh wouldn't it be great if that video could be found and we could see Susan visiting the pottery again and other shots of her in Cannes. I did try to "save" it but no luck.
