selectedIndex: This variable holds the index of the currently selected item in the image list. offset: This parameter represents the amount by which we want to navigate through the images. It could be either -1 (for navigating to the previous image) or 1 (for navigating to the next image). images.size(): This returns the total number of images in the list. (selectedIndex + offset + images.size()): This expression calculates the target index for navigation by adding the current selected index (selectedIndex), the offset (offset), and the total number of images (images.size()). % images.size(): This part ensures that the resulting index stays within the range of available images by using the modulo operator (%). If the calculated index goes beyond the last index in the list, it wraps around to the beginning
