I have a restaurant website that is in Joomla that I want to redo in WP. The user takes a picture of their new menu item with their smartphone and after answering a couple of questions (which enables me to determine the filename), they press enter and upload the image to the server. This image becomes the current image on the website. This image replaces or updates existing image pages. Of course, replacing images in the Uploads folder doesn't work with WP without manual intervention. My question is, how can I update the WP Media Library without manual intervention?
