Sample Credit Download Calculation:

Make 50 cents or $1.00 per normal image download - or much more on Special License downloads Whenever a person downloads one of your photos under our normal Image Usage Agreement, your account balance increases by 50 cents for smaller downloads or $1.00 for large file downloads. When your account balance reaches $30 you can request Paypal withdrawal to 'cash out' your account, or when you reach $50 you can request a check be mailed to you. 

Make up to $60 per download with Special Licensing sales If you have joined any of our Special License deals and buyers are purchasing your photos that way, you will earn anywhere from $2.50 to $60 PER download. 

There is unlimited potential for earning. We pay at this time $0.50 commission per 1 credit image sold and $1.00 commission per 2 credit images sold. Commissions are paid upon request as soon as your account reaches at least $30. If you decide to take part in Special Licensing (you should!) you can earn up to $60 per image download. Average Special Licensing commission is about $12 per image. We highly recommend you opt-in to Special Licensing.
