Hotspot is a plugin for easily adding annotations, text, or other stuff to an image, on the exact locations that you want. It’s an old concept with one exception. It comes with a powerful editor for precise drawing and positioning of the spots. You can also edit settings, see a preview of the final result and the editor will generate the HTML and JS code for you!
