Expand Image In Four Directions
The image can expand on hover in a choice of four directions - up right, down right, up left and down left.
It uses a single image rather than an image and thumbnail. The portion of the image shown in the widget is adjustable by applying horizontal and vertical positioning.
The image is contained in a figure element to allow a figcaption.
This, along with the alt text, makes for good SEO since the spiders know that the caption is related to the image.
Another advantage of this widget is that it will work on mobile devices using click to expand/contract.
