How can I upload a new photo (to replace one I have already previously uploaded)?
If you haven't requested any edits from us, you can simply click "edit" and go back to your card to personalize it like you did originally.
If you've already requested and received edits from us, you won't be able to edit like that, so if you click "view" next to your card you'll be able to get to the Proof Approval page. If you select the option for further edits, you'll also see a link there to upload a new photo, which will be sent to us along with your edit request. Of course, you can always email us your photo to email@example.com if you're having any trouble uploading.
