An object holding information about images in memory.
A GdkPixbuf is an object that holds information about a whole image (all the color values [red/green/blue/alpha] for every single pixel) in memory.
Pixbufs can be created by loading an image file via GdkPixbuf::new_from_file, by using a given GD image object as source (GdkPixbuf::new_from_gd) or just using the normal constructor, creating an empty image.
A GdkPixbuf itself just contains the information, it does not display it in any way. To display an image in your application, you most likely want to use a GtkImage which uses a GdkPixbuf as source.
