Every media organization, Jewish, frum or otherwise, should avoid changing pictures or facts to fit their viewpoint. For example, the Yiddish newspaper that edited out Hilary Clinton were right not to show a picture of her, but they should have blurred her out or cropped the photo, as opposed to making it appear as if she was not there. Firstly, this does show a lack of integrity that should be present even in frum publications (not that I believe they had an agenda, as many non-Jewish publications insinuated).
As regards the general issue of not showing any picture of women; It is obvious that most photos should not be shown, even if modestly dressed, as one does not need to be immodestly dressed for it to be a breach of tznius. But when it comes to children or older women (e.g. Rebbitzen Kannievsky), there is more of a question. But omitting even those is understandable. Not in order to be machmir, as others have suggested, but simply making a cut-off point. It is too much to expect from a newspaper or magazine to carefully adjudge each picture as to whether it conforms. it is far simpler, and commendable, to simply not publish them.
