Yes. Thats right. Bit you also have to tell the plug in where to look for it.

In WP go to OPTIONS in gallery. The click slideshow along the top.

Then you have to tell it location in “Path to the Imagerotator (URL)”
I just clicked SEARCH and it found it fine. Then started working from there. You can edit settings here too.

Hope that helps. Good luck with it.

I discovered I needed to install imagerotator.swf which I hadn’t realised before [doh] Details here if you scroll

Got it working fine. Unfortunately image rotator needs a commercial licence for comm site so had to switch it off for client, but it did work ok.
Hope that helps

I am also having this problem, and a client screaming at me for an answer ;-( All help gratefully received. Thanks
