I just received this email from Istock. Dear Contributor,

The following file(s) were recently licensed to an iStock customer in a transaction that did not occur through the website:

74740789
79379411

We have made an adjustment to your account and added your royalty from the license(s), which totals $1.44.

Sincerely,
The iStock Team

Does anyone know what this is about or why this even happens. I don't have any idea what image sold or what type of licensing it sold under. Should Istock not provide some record of the transaction?

Thnaks PB.
