1 credit = $1 or �1 or �0.57

They pay in which ever currency you request.  So think in US dollar and then they have a fixed exchange rate for � and �.

Does that answer your question???

...thanks CJPhoto & GeoPappas for your reply.
but... GeoPappas it doesn't stop at what you
explined. My understanding is probably Photographer
is getting lesser than that.

Every 1 credit image sold, Photographer gets 0.33 credit.
If lets say you manage to accumulate only 0.33 credit at
the end of the day,

At "My account" on the left box,
Fotolia says 1credit = 0.57 pounds
Therefore you are actually getting 0.33 x 0.57 pound = 0.188 pounds.
...which is lesser than 30% which you are supposed to be getting.??

Correct me if I'm wrong.

Thanks and regards.

YOu are getting 0.188 which is 33% of 57p and 57p is US$1

YOu are not taking into consideration the exchange rate.  Photos sell for 1 credit (and up) and you get 33% (and up) of that.  Then it is converted from US$ into �.
