You people just don't get it: the internet is about communication and sharing.
What's your website URL? If we "shared" a few dozen copies of it and killed your source of income perhaps you would "get it".
Some company used her image that someone put on Pinterest - for printed promotional materials, and the company is telling the photographer, basically, to suck it up and take it with the pinner who granted Pinterest rights to the photographer's image by pinning it.
Someone pinning something can't reassign the rights of the original author, that doesn't hold water and ignorance is no excuse on the part of the company using images that don't belong to them in the first place. I would simply send them a bill for the legitimate usage for the image, with a date that says legal action will be taken if they fail to pay before the due date.
If it has a registered copyright, they're toast.
If she has a common copyright, limited recourse.
Bottom line I'd talk to a copyright attorney and see what you could do perhaps naming Pinterest, the pinner and the company that used it in a printed piece but I'm not a lawyer nor do I play one on TV, so talk to a lawyer for sure.
Finally, I must ask the simple question, why in the heck is this photographer putting up images online with enough resolution to be used in a printed piece in the first place?
That's the first mistake, learn from it and move on.
