It's me again. Sorry :-)
Just one proposal. Could you include in next update a counter for images?
Something like 1/6 for Image1, 2/6 for Image2, 3/6 ..., 4/6 ..., 5/6 ..., 6/6.... There isn't one included right now, right?
Visitors don't know how many images are in the slideshow. If they are at the last photo and click again to next image, they start again at first photo. If they are not concentrated they don't know they have already seen that and are maybe a bit confused when they are beginning to recognize the same pictures again.
I know I could include something like that (probably very simple) in your code. But if you release a new update it would get overwrited.
