I have a feeling that rabbonim who feel it is improper to have pictures of women on the home walls (even wedding pictures), probably feel that photos in general are shtus. To digress slightly, I had a friend who is a mikveh attendant who once asked a rov (not her own) how to handle an inyan at the mikveh regarding nail polish that was hard to get off. His response: “What is this nonsense? Why should women wear nail polish outside?” First of all, that was not her question. Second of all, this rov is clearly a person who believes B’nos Yisrael should not wear makeup outdoors (yes, that followed the response about the nail polish).
Regardless of what a rov’s personal hashkafa may be, which should be respected, halacha should be based on halacha m’Sinai, and not whether or not a Rov holds girls should concern themselves with their public beauty.
As to the comment about a picture being improper because a husband and wife should not be photographed (even at the wedding) touching each other, there are Rabbonim who hold that the chosson and kallah should b’davka hold hands when they leave the chuppah going to the yichud room. To each his own, Kasha. If that is not your derech, by all means you should not do it.
