How is any of that different than posting the pictures on Facebook to begin with?
That's kind of a bigger issue. I'm not going to get into an entire discussion on it here, since I don't feel remotely qualified to discuss it in depth, and it's way outside of the forum's remit. But if you do a little research on it, you might find some very interesting points of view on it that you hadn't considered.
In summary, now that the Internet is such a big part of American society, there have been some discussions about children's right to privacy versus their parents' legal rights to post their image and such. This has especially been a problem with mommy bloggers and things like that, where parents have posted images of their young kids on a blog or Facebook page, either for monetization or just for social media clout, and then the kid grows up and decides the way their likeness was used is embarrassing or otherwise something they are uncomfortable with.
Legally, the copyright lies with the parent who created the image and who has the legal right to use the child's likeness, so the child doesn't really have much recourse, even after they're over 18. So it's possible such things can lead into a scummy situation where a parent is profiting financially off of "look at little Margie's poops" or whatever, and then the kid is suffering social stigma from it in their social circles, and has no redress because the balance of power firmly lies in favor of the parents. Which feels unethical to me, even if it's 100% legal.
Of course, the majority of instances of Facebook posts of children pose no problems, because the kid really doesn't care, or it's not something that would be embarrassing or feel like an invasion of privacy. But it's still something to consider; if I had kids, I wouldn't post any picture of them in a context I wouldn't feel comfortable posting a picture of an adult friend, which would include a quick "hey, is it OK to post this to Facebook?"
But then there's the question of what happens if kphoger says he has their consent. You have no way of knowing for sure, so it essentially amounts to "no photos of children", which should probably be included in the forum rules and guidelines if it's not already.
I mean, you're right, we have no way of knowing if the kids are okay with it or not other than the poster's say-so. So it's safer to just default to "not", especially since this isn't really meant as a service for sharing pictures of people or families anyway, so not much is lost by disallowing it.
Fortunately, road signs are public servants, so taking a picture of them doing their official job duties is a-ok.
