First time I,ve posted on this site. Thought you should be aware of something. It seems that a Czech site has a number of images from 123RF. In fact, they have my entire portfolio (at least they do credit my name).
The sitehttp://www.samphotostock.cz/index.php? may well be affiliated with 123. If they are, I'm not aware of it.
There have been a number of posts on the forum area of 123 relating to this site.
Regards,
Dave
