Sorry for not updating this thread - searching the older threads won't help because ZX Slideshow v3 is completely different and there have been no question about v3 yet...

It seems that you didn't assign your banners to the 'home' group. If you edit your slides, you'll see an input for "Slide Group". If you can't select home from the menu, simply use the input below and type in "home" (without the quotation marks). I know this option/requirement doesn't make much sense now, but I'm hoping to release an update soon which would allow to show different slides on other pages (ie. a slider specific to a certain category).
