I'm having the same issue. Using SlideShowPro, I've tried every proposed solution on this page.
I'm trying to embed my Flash movie into a Page, not a post, but in your FAQ, Kimila, you say that version 1.1 now supports embedding in Pages (and I'm using version 1.1, WP 2.0.4)
Kimila, you said:
Could it have anything to do with the K2 theme I'm using?
Here's my tag:
[kml_flashembed movie="http://www.chrishungate.com/wordpress/flash/slideshow/slideshow.swf" height="428" width="375" /]
and the URL works on its own so I know that everything's working with the Flash file. The darn thing just won't show up on my Page.
Please help if you can...anyone?
