Creates a new gtk.Image displaying the file filename. If the file isn’t found or can’t be loaded, the resulting gtk.Image will display a “broken image” icon. This function never returns NULL, it always returns a valid gtk.Image widget.
If the file contains an animation, the image will contain an animation.
The storage type (Image.getStorageType) of the returned image is not defined, it will be whatever is appropriate for displaying the file.
