Thanks Rick for this info and I'm pretty shocked. I didn't realise at first but when uploading an image, DA make this available for mobile desktops unless you untick the box. It could have happened this way but then again there's nothing to stop someone just right clicking over your image and saving it then uploading to their mobile. If your work is being sold as mobile desktops then I think you should approach the company, they have no right to do this without your permission.

I'm off to look at the website.

Thanks

Heather
