I do not view certain types of pictures of women as untzniusdig. When Rebbetzins Kanievsky or Machlis O”H passed away, their picture should have been in EVERY publication that posted a story about their middos and chessed. Our daughters need to see such role models. It is very relevant to show them pictures of women who are nashim tznuos, tzidkoniyos and accomplished.
Kol kvudah bas melech pnima, does not mean women have to be hidden from sight. You may as well do what the Muslems do, and put them in Burkas, if you believe that. If men have a problem even in the most innocent of circumstances, let them work on THEIR tznius, so they do not feel intimidated by the normal sight of even a frum woman whose life was devoted to doing chessed for others.
If one is talking about pictures of women, which clearly are meant to be attracting in their nature, then I could see and even concede that point to those who feel strongly about it. But when pictures of little GIRLS are being edited so they appear faceless, we have taken this way too far, in my opionion.
