Please note that my answers have nothing to do with WebIQ here, but are valid for any other website as well: 1. You can detect if an image could not be loaded using JavaScript 2. If you'd try to use a local URL like file:///C:/Users/username/Downloads/icon-2024-150x150@2x.png in your HMI it will not work because: a) a webbrowser does not allow local access for security reasons b) That path would be local to ANY HMI user, not from the server, i.e. if you'd open the HMI from a tablet it would never work as even tha path c:\ does not exist there I don't understand on what you're trying to achieve here, can you please elaborate on what you are trying to achieve rather than the solution you are thinking about. Is it about users uploading new images through the HMI?
