re: the photoshopping issue. I agree with those who say the intent is to not have untzniusdik pictures around and not to rewrite history.
I think the reason why sometimes people have a problem with this might be because they feel that it is important that people know that some people didn’t dress tzniusly (in certain ways) then, so that they can “prove” that tznius in not so important, and it’s a modern-day invention.
Otherwise, who cares? Why is it so important to know that some girls didn’t dress tzniusly in certain ways? It’s certainly less important than making sure that we are tznius and don’t look at these pictures.
And if you really think it’s that important, the books talk about it. You don’t need to see actual pictures. How do I know that women didn’t used to cover their hair? Because it’s written in a lot of books.
