Contact
One inbox for everything: images, purchases, refunds and reports. We reply by email.
Help with a purchase
If images did not appear after paying, or you want to use them on another device, include the email address you paid with and the order number from your Waffo receipt (it starts with ORD_).
Refunds
Unused images are refunded within 14 days of purchase. Send the order number. See the refund policy.
An image went wrong
Tell us roughly when you made it, your browser, and what you saw. Images that fail are not charged; the credit returns by itself.
Report an image
If an image made on this site shows you without your consent, copies your work, or breaks the acceptable use policy, write to us with a description and where you saw it. We reply within 3 business days.
