One problem would be people stealing others images for profit.
Earlier quoted context omitted.
I thinks it is pointed in: -Photos for sale are identified as rightfully owned by having RAW file details published to the blockchain (actual High Res image is not stored on chain)
Technically there is no reason why you couldn't create a raw image from the jpeg, difficult not impossible. Then the only benefit is the creator has got proof of the creation date, the pirate couldn't prove they created the content before that date.

Call me a cynic, but can't I change a pixel and use the photo w/o the copyright?
Next feature to add, or deriving business to create: add an indexer/comparison service that checks the JPEGs and to see how similar any two given pictures are, and if one derived copy sells anything, the creator of the original picture gets notified.
I don't see the way how this could be implemented to blockchain. If every blockchain node downloaded and compared all images It would create massive bandwith and need for cpu/gpu power. Or am I missing something?

The remedy, in other words, remains legal. I see this as a tool for facilitating legal remedy. (Or have I missed your point completely?)
> Photos for sale are identified as rightfully owned by having RAW file details published to the blockchain (actual High Res image is not stored on chain) Does anyone have a clue, how this should work? Eg, if I just 'steal' a pic and change slightly its brightness, color curve, crop, blurriness, etc. will the system still be able to identify the original? Otherwise great idea.

This could work from buyer/client side. If I want to buy image, I will check it with some service to be sure that I don't pay to pirate(newer&lightly changed image). But what If buyer doesn't use it? I don't see the way how this could be implemented to blockchain. If every blockchain node downloaded and compared all images It would create massive bandwith and need for cpu/gpu power.

I would imagine you're buying a copy of the photo in non-raw format, whether it be jpeg/png/whatever. If you don't have a RAW copy to post to the blockchain, it's impossible to steal it.

It is good to design systems with the assumption that most users will use them as intended. There will always be misuse, but that can be adressed later if the system is successful. Compare airbnb, uber, dropbox. They all have very bad use cases. The systems were designed for the vast majority of users being lawful and for the most part it works.

are you sure .PNG doesn't contain enough data to reconstruct a RAW file? I'm not...
*Possible in the mathematical sense, it may not be practical.

I am assuming they hash the RAW file. Since JPEGs contain less information than RAW I don't think it is possible to get from JPEG to RAW to hash value matching the one from the original RAW.
