To delete an image,
tkDerm permits only the user who logged in as the tkDerm superuser to do this action because it will delete the image file.
When you log in as a user other than the tkDerm superuser, the Delete button will remain disabled even if you select a thumbnail.
tkDerm superuser means the user who initialized tkDerm. See Section 1.7 ( page).
The image that has been deleted cannot be restored. Be sure that you intend to delete the image before clicking the Delete button.
