When no further retouching is needed, it's time to approve the image. When an image is approved, all project collaborators that do not have notifications muted for a project will receive an email and in-app notification.
To indicate that the retouching is locked in, follow these steps:
Click the Approve Button: When you are satisfied with the retouching, click the approve icon.
Confirmation: The button will change to green, signaling that the image has been approved.
Visual Indicator: when you navigate back to all project images, the image thumbnail will have turned green and reveal the word "Approved"
