I am not sure if this has been done or can be easily accomplished,  I have had the request for the last image to link to the first image when you click next.  I would like the images to be circular.

Lets say I have 6 images in a simple image gallery.

when image 5 displays the previous image would be 4 and the next image would be 6

when image 6 displays the previous image would be 5 and the next image would be 1

whem image 1 displays the previous image would be 6 and the next image would be 2


If anyone needs further clarification I would be happy to provide it.

All solutions and comments are greatly appreciated.

Thanks in advance
