After seeing this demo on dablet.com I thought that I might put this method to a useful purpose, so here is my demo which uses the same principle.
Hover the image to see an array of pointers overlayed on the image with an opaque rectangle beneath. To the right there will be a large image showing the section beneath the opaque overlay.
Click and hold the mouse button on any of the arrows to move the opaque overlay in that direction and then release the mouse button to stop the movement. The overlay will stay positioned and the large image will reflect the newly selected area. Click and hold the center circle to move the overlay back to the center of the image.
Moving the mouse off the image will close the large image and the controls, and if you hover the image again it will remember the last position selected.
Because of all the time and effort spent in producing this demonstration I would ask that you respect my copyright.
