independent of this case, is there a technical possibility to put amateur reusers in future on a safe ground.
The only foolproof licence is CC0, which gives away all rights to the user and keeps almost nothing for the author himself. But CC0 neither is a CopyLeft licence that perpetually secures the freedom of this content (Everybody can take CC0 staff and publish it in a proprietary way wit no attribution what-so-ever), nor is it a good argument to convince professional or semi-professional contributors to publish there quality work under. Hence CC0 is more a problem than a solution.
Beside that, I don't think that it is our prior duty to offer "save ground" to any kind of reusers. A lot of licence violators honestly don't give a shit about free content. They just don't care about copyrights and have no respect to the author, who created the stuff they are using in the first place. I definitely don't want to support that.
By automatically adding author and license info into the metadata of the image. If this is not enough attribution we should strive to have this kind of attribution accepted in a future version cc license.
An attribution only inside the metadata is not compatible with the licence's requirements, mainly because it can't be read in every browser without any add-ons and digital forensic skills.
The CC-licences require the attributions to be "at least as prominent as the credits for the other contributing author".
Furthermore a lot of CMS remove such metadata automatically while scaling and recompressing images.
Without the need of education.
Education is the only promising approach to prohibit license and copyright violations.
We need to teach people, that our content is not "free" as in "free beer" but "free" as in "freedom" and that freedom comes with responsibility. Namely the responsibility to give reasonable credit to the author of the work (you want to use) and reference the license (that allows you to use it).
It is neither possible nor desirable to take that responsibility from the users.
