Interesting question.

I take a photo of Liebling, e-mail it to a family member. I would not object to this photograph being e-mailed on with my knowledge, as if family love Liebs enough to want photos of him they like to share. I rarely e-mail photos. As in, I think I have done it twice.

I take a pic of Liebling and it goes on Facebook. I have to acknowledge that is shareable. For some reason, no-one has shared (unlike the e-mailed ones, which were sent to people I had never met then I was told about it afterwards).

I give a hard copy of a picture. You can show it to others but copying it for others would not be correct etiquette, IMO.

MiL takes a picture of Liebling. She can do as she wishes with it, she took the photo. I really wish she wouldn't take photos, especially as she loves the "no pose" type when I've just taken a mouthful of cake or am turning around to take to someone and look really gormless. On *every* photo. OK, it may be I just always look gormless but I hate her photos. I have asked her not to undress my son and photograph him but she still does (but not her other grandchildren). Thankfully, she asks DH to remove the photos from her memory stick and put them onto a DVD-player readable CD so she can show others. Those ones do not go on the disc. I also take copies of all Liebling pics as she is aware that DH needs to copy them to his computer first, so that's fine. I do not keep pics of anyone other than Liebling, as that is not appropriate.

If I had family I did not want to see a picture, then family members still in contact with the ones I did not like would not be receiving photos. Just safer that way. (Plus neither my mother nor MiL is good at not over-sharing anyway so I'm generally cautious about the photos I give out - these days, only school pics and haven't uploaded to FB for months.)
