I've added the code at the top of the page and I get nothing.
Still a blank page.
I can say that the Power Gallery works perfectly on my live server, but not with WAMP.
I want it to work on WAMP server also, because I can not work on both my test server and live server simultaneously. I have much more to do on my pages than simply adding up the Power Gallery. And it becomes much harder to work with layout and graphics are not true.
So what to do?
