When I upload a picture or video to a dropbox folder that is a subfolder sorted into days within an umbrella folder (manually - only a couple a day) - how do I automatically embed the most recent .jpg/.mp4 of any of the subfolders into the website. Purely displaying the image or video itself and not the list of what is in the folder. Many thanks (don't understand any of the API stuff so some HTML code that I can change account details within or something simple would be super appreciated)
