Image Annotator

If you've ever wanted to draw on an image or add a caption or text to your image then this is the plugin for you. Best of all it allows you to add your caption, save it, display it, then go back and edit it in different layers and objects laid on top of your image.

It extracts the text from the annotations and displays them as selectable and stylable text just below.

You can hold shift as you draw rectangles to make them perfect squares, same with the ellipse tool and circles.
