I was wondering the same thing, and just asked the ICAN list that I am part of, whether graphic photos of my "en caul" 10+ lb HBAC would be perceived as appropriate and interesting, or offensive/too graphic. My photos are cropped to show only the points of interest (no identifying parts) and I think the emerging head still encased in the sac is of interest, as is the closeup of the nuchal arm, as well as the fact that it was a large homebirth after c/sec. Would love to share it, yet not sure of the ramifications.
Thanks for asking, and we will both hope to hear from someone who may know.
