Today, I revised the skill of inserting a link into a part of an image using Google. I have been unable to insert the image with the link into Google blogger but it does work well embedding into a Google site, and is updated as you make any changes to the original drawing.
I used "Google Draw" polyline to draw a shape around myself, make it transparent, and then inserted a link to my Google+ profile. This image can then be "published to the web" to be placed in your site. This could be useful at schools so that students could just click on parts of images to take them to another website that you wish them to work with. For example, a picture of a number of books with each book spearately linked. Here is a screencast of how to do this.
