Step 1 Create a new image map
To create a new image map, click New on the top-left of the editor, enter a name and click Create.
You can choose to have a responsive or fixed size of the image map. To change that, click Settings. From the menu on the left, choose General. The Responsive setting is automatically enabled. If you want to set a specific size, you should disable it and enter the desired width and height in pixels.
Keep in mind the real size of the image which you will set as a background in next step. If you set a different width/height ratio you can stretch the image and it will look bad. After setting an image in Step 2, you can always come back and click the Reset Size button.
