Hi all,
looking for my images in use I found a site that attributes all stock images with Creative Commons (CC BY-NC-SA 4.0). I guess they have downloaded legally from fotolia or shutterstock.

Examples:

http://www.iha.co.in/Holiday-lettings-Faial-island-Guest-house-bed-and-breakfast/oP*/
http://www.iha.co.nz/Playa-del-ingles-Last-minute/i4Z/
http://www.iha.com/Short-term-rentals-French-west-indies-fwi/2R/

There's a dozen or more others from my portfolio and I can imagine that a lot of other MSG members are affected.
I already reported misuse to the site owner via contact form, but that might not be enough, especially since I'm not sure from which agency the images are bought.

Any idea what to do?
