Image upload provision when dragging and dropping a shape on canvas from palette

Hi @walter, Greetings!
Is there any possibility to give a provision to upload image? I mean like we have in html , which opens a dialog to upload an image from our sysytem.

GoJS only provides diagramming functionality. You can implement an “ExternalObjectsDropped” DiagramEvent listener to get an event when the user drag-and-drops from a Palette to a regular Diagram, but you have to implement any file upload functionality in HTML/JavaScript in cooperation with your server.
