* An object that allows one to show an image which other process created.
* It can be used anywhere like any other elementary widget.
*
* This widget emits the following signals:
* @li "clicked": the user clicked the image (press/release). The @c
* event parameter of the callback will be @c NULL.
* @li "image.deleted": the server side was deleted. The @c event
* parameter of the callback will be @c NULL.
* @li "image,resized": the server side was resized. The @c event parameter of
* the callback will be @c Evas_Coord_Size (two integers).
*
* @note the event "image,resized" will be sent whenever the server
* resized its image and this @b always happen on the first
* time. Then it can be used to track when the server-side image
* is fully known (client connected to server, retrieved its
* image buffer through shared memory and resized the evas
* object).
