Hello, I have been able to drag and drop images from a toolbar to a html5 canvas. And now i need to connect two images/objects with a arrow. Basically the scenario should be, when you click on a dragged object, conncetiong points should appear and by dragging one point to another point on another image will cteate a arrow. Can anyone help me on achieving this? Thanks in advance.
