The ImageList_Add function adds an image or images to an image list.

int ImageList_Add(

HBITMAP hbmMask	// handle to the bitmap containing the mask
);

Parameters

hbmImage

Handle to the bitmap that contains the image or images. The number of images is inferred from the width of the bitmap.

Handle to the bitmap that contains the mask. If no mask is used with the image list, this parameter is ignored.
