This plugin is designed to easily create image maps (aka "hotspots") on any image that you have inserted in CKEditor.
After selecting an image you can draw over it the active areas that you want to link in that image, and you can use rectangles, circles or free form drawing. It generates the standard HTML codes like <map>, and <area>, there's no special requirement to use this kind of effects.
Those hotspots are highlighted in the image while the document is being edited, so you can easily recognize that this is an special image.
The plugin is compatible with CKEditor 3.6 and 4.x
