Hi can someone help me understand the Fotalia credits and what I actually get per image?

in the last week I have had 4 downloads - 1 was for a large image = 3 credits and the others were for 1 credit each. It shows that 1 credit = 57p but where my credits in my account are listed it reads �1.98 - Is this in pounds? or is this in credits? is this after Fotalia have taken their cut and what I am left with?

I havent been on there long so don't quite understand the credit system - Bigstock is a bit more straightforward.

thanks

Thanks that explains it - so I guess they are pushing people to be exclusive and therefore i don't get paid as much - but i guess I should be happy I have finally sold some 

Thanks for your help
