Re: Taking pictures - again
On this last part, I think almost everyone would allow medical imaging as a matter of neccesity.
All scholars are united on the principle that neccesity overrides prohibition. An example is the Taliban themselves. Whilst believing photos to be haraam (hence you never had any official pictures of Mullah Omar or other Taliban leaders), the Taliban insisted on people having their photos on ID documents - because they felt the neccesity overrode the prohibition. It even went as far as forcing women to show their faces in ID photos.
Naturally, of course, only female Taliban officials were allowed to look at those women’s ID and check if the face under the burqa was right…
