Just found a lot of my images on their site. As they are sold by subscription only, it is quite possible they are there legally (e.g. partnership with some other site, though I could not find any exact match).
What bothers me - their copyright info. All my images say
Photographer Fotosearch Subscription
I know that there are a lot of people in this group who are pretty fluent in related laws. So my question is: even if the usage is legal, isn't such copyright notice a violation?
