You mean all overlapping each other?  You can only display a single "flat" image (animations not counted).  
So if they're one ontop of another, you need to composit them together into a single image.

The preferred monster, is;

void gdk_draw_pixbuf (GdkDrawable *drawable, GdkGC *gc, GdkPixbuf *pixbuf, gint src_x, gint src_y, gint 
dest_x, gint dest_y, gint width, gint height, GdkRgbDither dither, gint x_dither, gint y_dither);

... or, if you don't mind using depreciated functions ...

void gdk_pixbuf_render_to_drawable_alpha (GdkPixbuf *pixbuf, GdkDrawable *drawable, int src_x, int src_y, int 
dest_x, int dest_y, int width, int height, GdkPixbufAlphaMode alpha_mode, int alpha_threshold, GdkRgbDither 
dither, int x_dither, int y_dither);

(I didn't actually know the latter had been depreciated...  Seems they've ditched the alpha_mode and 
alpha_threshold, and added a gc instead.)

That's basically your main tool.  Composit them all together, probably into a new image of the appropriate 
size (unless you don't mind trashing the one at the bottom of the heap) and stick the result into a GtkImage 
or equivelant.
