Background Type Slide Show does not work

I modified the images bgX.jpg, bg_staticX.jpg ... as instructed by the site, but now no longer run the slideshow.
It is only the image being displayed bg_static2.jpg and never shifts to the other.

My parameters are:
Background Type = Slide Show
Background Color = # FFFFFF
Static Background Image = bg_static.jpg

What should I do to make the slideshow run properly?

If you set static background that turns off background switcher , if you wanted to replace backgrounds used by switcher you should replace:

templates\hot_destinations\images\bg1.jpg
templates\hot_destinations\images\bg2.jpg
templates\hot_destinations\images\bg3.jpg
templates\hot_destinations\images\bg4.jpg

Ok, but I replaced the images as you said, but even with the "Slide Show" is selected in the "Background Type" the switcher does not work.

I need to make the switcher works!
See attached my current settings.
Even with them my site shows only the image "/templates/hot_destinations/images/bg_static2.jpg".

Send link, we can do nothing with snapshoot

are you sure Background image is set to "Slide Show" ? because script for that is not even loaded
