Re: wedding photos by so called professionals.
Yes quite complicated-eg If on here I post direct links to another site - who I guess have the same T&C who also claim the copyright where does the claim lie?
I suspect that the claim of copyright by these online sites is a heavy handed way of protecting against legal action.
So I post an image online - the site server has as expected a backup system- I could take a legal action to say that the site had made an electronic copy of my image without my consent.
So I guess the T&C statement albeit a bit draconian , protects the hosting site. As I said before-highly unlikely that the hosting site would dare to actually breach Intellectual Property rights.
Still as I said a bit draconian- don't show me your holiday snaps if you visit my home or I will claim them for myself.
Posting a photo by posting a direct link to a photo hosting site seems like money laundering affair!
