Canepar-- I know I've posted this before. I was in contact with Yvonne Craig, and she sent me a lengthy e-mail discussing tickling and other things. She said she is NOT ticklish (Arrrrgh!) and that she's been asked that questions many times. She said her mother is very ticklish, but that neither she nor any of her siblings were ticklish.
I'm a fan of the old series and would be interested in seeing your picture. I don't recall the episode, so perhaps it is a promotional picture.
