Thanks traveler and Racephoto.
Today i do more search on my subject, and i found at least 3 more contributors, one of them has a huge portfolio(28k).
I am just a small nobody, do you think they will listen to me ? Some sites i am not in yet, not sure how am i going to contact them.
I already try to reported some... but i don't know should i continue...

Hi Arquiplay77,
 i never think of this would happen as well, but it did happened. And there is no currency conversion. USD to USD.
ThomasAmby,
May i know you notified Fotolia or Paypal ? Do they ask you to provide anything ?

Thanks

Thanks you all guys for the support.
to Lisafx and Fotografer, you don't have to apologies i think. After all we are in the same boat and it's really not easy for others to notice.
I can spot it just because i spend many hours on this file, and it's my very 1st file approved in microstock .
At Istock his files has gone. i received a 2nd mail from admin, (thanks Mr.Locke ! i think its you.)
Still no respond from others agencies yet.
Will update you all if you still want to know the outcome.

Thanks Gostwyck.
At first i just noticed the file at Istock, and when i see that he/she only have 4+ files, i did contact Istock support.
And the respond from Istock:

"I would first like to say that I do understand your concern regarding this matter and we do take this seriously.

In order to protect works in such a way that doesn�t preempt future works, copyright protects the expression of an idea, yet not the idea itself. If copyright extended to the underlying idea and granted exclusive rights in an idea to one author, it would ultimately discourage thousands of original works for every other person.

Some of the very first �water on white background concept� images on our site date back to June of 2005.
Examples are 654751 and 656608.
Your portfolio starting adding this concept of files approximately August of 2007.

As I am sure you can understand, this is a very difficult situation for iStockphoto to enforce. We are not in a position to say that member�s cannot submit an image because another came up with the idea or concept before they did. I do hope that you understand this position and that this email has provided clarification on this matter."

After that i did go to other sites(at least 10 others sites) to check... and found at least 8 others images from 2 of my images at all sites.
I post it here just to see whether anyone of you have your image taken by him/her.
If only mine was taken, then i might send her a mail ask her to take down those affected images, because i found that she has 2+++ files at SS.
Because of a few not good seller, she might has to pay a heavy price....(2000 files is not easy).
Is this good?

Thanks
