This is news to me, its the first sale I’ve had marked like this  “Credit for Photo Sale by reseller”…
Could this be how the Fotolia Free API works??
The Pics below:

http://futureworks.co.kr a Fotolia Reseller in Korea, is a Flash website, but I couldn’t spot how to purchase images.

The recent Fotolia new letter:
“COMING SOON: FOTOLIA’S FREE CONTENT API

The first website based on the Fotolia’s free content API will soon be released! The site will drive traffic to Fotolia and is a fantastic opportunity for Fotolia’s contributors to get additional visibility amongst stock photography buyers.

Fotolia’s extensive API infrastructure (partner, Business, Developer and Reseller) has already shown their capacities in driving qualified traffic on the Fotolia website. We’re confident that this new API will do the same.

As a backgrounder, Fotolia’s free content API is based on free contents and unsold files. This API will be used by Fotolia to attract more stock imagery users and to invite them to buy additional imagery on Fotolia. That means: more traffic, more buyers and more sales. As you already know, you can add your unsold files to this program and get a half credit for each file added. Your file will be still offered on Fotolia.com at the standard price, while at the same time, being offered for free through the API.”
