Use an iterator.  Here's a code snippet:

  /*
    Read an image.
  */
  magick_wand=NewMagickWand();
  status=MagickReadImage(magick_wand,argv[1]);
  if (status == MagickFalse)
    ThrowWandException(magick_wand);
  /*
    Turn the images into a thumbnail sequence.
  */
  MagickResetIterator(magick_wand);
  while (MagickNextImage(magick_wand) != MagickFalse)
    MagickResizeImage(magick_wand,106,80,LanczosFilter,1.0);
  /*
    Write the image then destroy it.
  */
  status=MagickWriteImages(magick_wand,argv[2],MagickTrue);
  if (status == MagickFalse)
    ThrowWandException(magick_wand);
