The photo upload failed. You will need to submit one print photograph meeting requirements, stapled or glued to the online DS-1648 confirmation page. See the print photo format found in the Nonimmigrant Photograph Requirements. If the confirmation page includes a photo image, then the photo upload function has succeeded and no separate print photograph is required.
