[Plugin: WP Photo Album Plus] My slideshow does not work.

It works to me. Clear browsercach or so?

Thank you for answering.
The gallery works, but when click is done in the arrows the thumbnail does not move.

On my computer it does. The big << and >> as well as the << Previous photo and Next photo >> links. Try a different browser…

Thank you.
I have realized that if it works with Internet explorer and firefox, but not in google crome.

wait could bear in mind this, since crome is nowadays the browser most used.

Thank you for everything.. Excellent plugin!

I will check it in chrome…

Your site does not work properly (the filmstrip) in chrome indeed.
My docs and demos site works also in chrome:

I see you use lightbox-plus. Try lightbox-3 that is known to work with wppa+

Do you really also need nextgen?

Try de-activationg other plugins, that may help
