The format of the AppendImageToList method is:

AppendImageToList(Image *images,const Image *image)

A description of each parameter follows:

A description of each parameter follows:

images

the image list.

exception

CloneImages

CloneImages() clones one or more images from an image sequence, using a comma separated list of image numbers or ranges.

The numbers start at 0 for the first image in the list, while negative numbers refer to images starting counting from the end of the range. Images may be referred to multiple times to clone them multiple times. Images referred beyond the available number of images in list are ignored.
