what do you do if you find your images used by companies without permission? i just found several images on a webpage of a company, withoiut that they asked or bought the rights and without writing my name under the images. are there lawyers in the US who handle such abuse or how you do it to get your money fr this (ab)usage?
I use Picscout service. They also have lawyers you can contact if you find anything yourself but you have to be their client first I believe.
There must be other collection agencies who specialize in it.
Grab screenshots and save the pages first. Make sure it's a commercial web site, not just kids taking images from google. If it's a commercial site contact them with a letter and an invoice, otherwise, ask to remove the images. Keep all the correspondence. If they refuse to pay the fee contact a collection agency they may help negotiating the deal.
But to get the matter to court you'll need your copyright officially registered before the violation took place. And it must be a significant sum of money, otherwise you'll lose more in legal fees.
