I found one of my images on a website last weekend that hasn't been registered as sold in my sales history (yet). It had my full credit, and it also included five other fully credited Alamy pics, so I'm assuming that it's on the up and up. In addition, the Alamy form for unauthorized use says: "Remember, some customers confirm use after publication so it might take a few months for your sale to be processed".
Still, it's the first time I've found one of my pictures before it's been reported, so I'm wondering if this is common, and how long others have had to wait before it is reported.
