And  what  shoul  a  "XXL"  one  bring?

Something you can't say on TV.

It's an extra extra large TIFF file - they upsize the largest JPEG to offer it at 10 credits

     Yeah  but  i  was  looking  to  see  if  they  paid  the  right  commission.  Several  on  here  have reported  mistes  -  so  i  wanted  to  be  sure.

They have said the minimum buyer price per credit for the purpose of calculating royalties is 40 cents. So at 50% royalties, that's 20 cents a credit, at 45%, 18 cents, at 40%,  16 cents and so on. Work it out for your royalty rate

     I  looked  at  the  numbers  wrong.  I  thought  it  was  .267  (27  cents)  but  it  was  $2.67.
  I  can  take  tat  better  (stll  not  sure  if  that's  right  for  10  credits.
Thanks  jsnover  for  the  help.
