This is so close to what I was hoping for except the one small failing that all I can produce is a black box with no images.
In 'Manage Slides' I get the 'no image' icon for all images after upload. If I click on one, I get a preview of the slideshow I was hoping for.
When I view a post with the shortcode, I get a black box with previous and next rollovers but nothing happens. Images are in uploads/slideshow-gallery folder and filename is in database.
The same thing happens on a clean wordpress install using the default template.
I have wasted ages but it will be worth it if there is support to get it working because it is beautifully simple.
