with views you can select under Theme Information the custom template file. I've copied the original
views-slideshow.tpl.php to my custom
It works after you flush the cache. But only once. If you refresh the page (F5), then you get these errors:
Notice: Undefined variable: skin in include() (line 16 of C:\Inetpub\wwwroot\123.com\sites\all\themes\andalusiah\templates\views-slideshow--featured--pane-featured.tpl.php). =>
> Notice: Undefined variable: slideshow in include() (line 24 of C:\Inetpub\wwwroot\123.com\sites\all\themes\andalusiah\templates\views-slideshow--featured--pane-featured.tpl.php). =>
The problem is that $skin and $template are no longer available in the custom tpl file. If you refresh caches one more time, again it works. But again only once - after you refresh the page again, same errors appear.
I'm showing this view as a content page within panels, but issue does not seem related to panels. It probably points to a tpl file caching issue.
