Probably most of you already know that in FT, there is a section called credit details, where you can click and find out who bought your image, yesterday i found out one of my least favorite image was used in a French Newsletter, too bad it's a PDF file, I can not show here, but here is the link:

the i van against Mount St Helens is my picture.

How do you find out other sites, I understand most sites don't give you the name of buyers, so for FT is a little strange, but goo to know who purchase your photos

As far as I know, FT is the only site that does that. It seems most of my sales there are in Europe. Haven't found one yet.

i have had luck finding my images by searching in google.  I just type my name in and then click on the images link.

Yes, Fotolia is either FT or FL

I only found one, after a google search for finding who the FL buyers were, then I emailed them to thank them for buying the picture, and they were kind enough to send me the link of their site (a martial art club) where they used a cropped picture on top of their home page club news.  They even showed me the templates with the before and after rendition.  Indeed, very nice anglo-saxons..!  Here it is:

Note: it's my children's tae kwon do belts, not mine...
I don't try to reach people anymore, but still check once in a while to see who buys the pictures.
