How do I delete a photo from a submission

Currently the only way to do it is if I attempt to forward it to someone else. When I click on edit on the page and attempt to delete the photo, it looks like I can only do it by replacing the photo with another

Hi,

Unfortunately, you cannot delete the photo by just re-submitting the submission. You have to delete the entire single submission if the purpose is to free up your file upload storage. If the purpose was deleted, let us know so we can further check of a possible workaround.

Thank you!
