Hi Stephanie! Event organizers are not able to add additional pictures to an application after it has been submitted. This is something the vendor would need to do on their end by following these instructions: https://help.eventeny.com /hc/en-us/articles/8367772264987-How-to-Edit-Picture-Information-After-Application-Submission-as-an-Applicant" target="_blank" class="link text-blue">https://help.eventeny.com /hc/en-us/articles/8367772264987-How-to-Edit-Picture-Information-After-Application-Submission-as-an-Applicant However, you are able to edit the submitted picture information by going into the vendor application, scrolling down to the submitted pictures, and clicking the "Edit Info" button next to the image you would like to edit the information for. I hope this helps! If you have any questions please feel free to reach out to support at https://help.eventeny.com .
