Dan, with all due respect you lack knowledge in halacha. Tznius is a halachic topic not a CH topic. Yes there are halachos regarding looking at (even!!) pictures of woman. The fact that you are not aware of them does not change them. The fact that certain people photoshopped instead of cutting it out does not change the halacha. Certain things are assur.
As a lubavitcher it's easy for you to pull out "mivtzoim" as a blanket rule that everything is muttar, those that actually do mivtzoim can attest as to how bad it is. They only fo it because they say the lubavitcher rebbe said he took responsibility.
Regarding pictures there is a back and forth between rav gavriel tzinner and the Lubavitcher rebbe.
The rebbe allowed:
1) black and white
2) photo
3) of the Rebbitzin ,
3) whom nobody really knew
Still it is מדת חסידות להחמיר however in this case we could print it,
4) because it can add to והחי יתן אל לבו

Sounds like a fair argument. I don't think any Lubavitcher's would want to argue with the Rebbe. I have seen this conversation although I don't recall exactly where. I'll try upload later.
And that's why the beis din of CH came out with a psak that COL is assur due to pics of women?
Oh wait they didn't do that? Maybe what's halacha and what's minhag are different.
Don't get me started on COLlive. They're a bunch of individuals who have no regard for respect of Rabonim, Jewish law and lack many other basic Jewish values.
I would say that the reason why the Rabonim of CH didn't put out a letter against it is because they wouldn't listen anyway but apparently they did sign a letter as koplonko showed us (surprisingly both Rabonim on the same letter).
Bottom line: If a rav gives a psak, wether it's based on halacha, minhag or hashkafa, should have an equal bearing and we can encourage Chareidi news outlets to follow even if some people will think we're crazy.
