Hi all,
There is a new version of the slideshow_flash plugin available, which should be compatible with Zenphoto v1.2.7+ (new plugin folder structure etc).
If people with v1.2.7 or later of Zenphoto installed can give this a try and check it works I'd be grateful, as although I've had time to fix up the code, I haven't had a chance to upgrade my own Zenphoto install yet to test it. Feedback gratefully received!
Thanks all - and thanks to the people in this thread who identified the problems and how to fix.
Thanks,
Mark
