After a photo has been rejected manually, or it has been rejected automatically by the system, the photos will show up under this pane.
To allow for a Stand user to upload another photo, you will need to delete the rejected photo. You can do this by selecting the photo(s) you would like to delete from the list, then clicking on the Delete Photo button at the top.
You will need to confirm the delete operation. Do note that deleted photos are not recoverable.
If the photo has been mistakenly rejected, you can select it, then click on the Approve Photos button, or the Thumbs up button to the right of the record in the list, to move the photo into an Approved status.
