I don't understand your numbers - why are all the subscriptions $0.24? I thought it was a flat $0.35 for every file (except for the $2.00 short/limited/whatever special ones).

Jan 24th - 13 credits - 1.66$ (0.127$ per credit)
Jan 30th - 15 credits - 6.26$ (0.417$ per credit)

Yes, about half of them are o,24$  lately and half 0,35$ and don't get that either.

Isnt there any official list of what we are getting out of what on DT ?   

Just read other topic mentioned, and more or less it was left  on wondering point if Im not missing something ?

24c is what you get after 30% US withholding tax has been deducted from your US subs sales because you live somewhere other than the US, unless there is a special treaty arrangement.

That could be it  didnt thought of that , was thinking that that happens before I request payout like on most other sites.

What is a "Credit"?
What is the value of a "Credit"?

A Dreamstime Credit has not the same value as a Fotolia or a 123RF one.

The "Credit" is not an universal currency.

Take it further - the same agency's credits are not of equal value, some come from big, cheap packages, some come from small expensive ones. And on DT credits from the same package generate different commission percentages, depending on what image they buy and how often it has sold. The number of different values credits have is the number of different price-points they are sold at multiplied by the number of different commission percentages that the site pays. In DT's case I'm sure that runs into scores of different values and it might be more than 100.
