Image Options On Downloads

If you allow image options on download purchases, how are you delivering the final photo to the client? 
In general, I want school photos to be available for instant download after purchase, so I don't need to approve each one. But if they purchase touch-ups, I'll need to provide them with an updated digital file.

you can only pre-warn customers that retouched images may take a few days and replace original image when ready.

You can replace the photo on the order with the edited one and then email them it is available. Click the Manage Photos tab when viewing the order in the admin.

Perfect! That is how I have done it in the past when I manually approved each download, but I wasn't sure if it would work if they have already downloaded the first version.
