It would be great of this could be fixed in an update:

What I mean is that the transition could be smoother

What you mention is the interval time between showing the next image, but I would like to know a way to be able to make the transition itself slower, smoother.

Here is a website still in V9 with the kind of smooth transition I talk about.

http://www.zealand-shipping.nl/en/

This was flash, now its HTML5. Here a converted V9 to V10 where you can see that the transition is much abrubter than with the V9:  http://www.winkel-en-object-beveiliging.nl/honden-brigade.html

I am aware of the downsite of using flash, but encounter some clients who wanted me to undo the V10 of their website just because of the transition in the slideshow. Is there any way to make this happen with the HTML5 version of the gallery I wonder?

Kind regards, Annie
