* @Short_description: A widget displaying an image
*
* Sometimes an application will want to avoid depending on external data
* files, such as image files. GTK+ comes with a program to avoid this,
- * called <application>gdk-pixbuf-csource</application>. This program
+ * called <application>gdk-pixbuf-csource</application>. This library
* allows you to convert an image into a C variable declaration, which
* can then be loaded into a #GdkPixbuf using
* gdk_pixbuf_new_from_inline().
