-/* Images
- *
- * GtkImage is used to display an image; the image can be in a number of formats.
- * Typically, you load an image into a GdkPixbuf, then display the pixbuf.
- *
- * This demo code shows some of the more obscure cases, in the simple
- * case a call to gtk_image_new_from_file() is all you need.
- *
- * If you want to put image data in your program as a C variable,
- * use the make-inline-pixbuf program that comes with GTK+.
- * This way you won't need to depend on loading external files, your
- * application binary can be self-contained.
