I've installed the plugin uploaded images and created a slideshow and then put the php code in my file.
When i load the page i am able to see the divs and the java script loads as well but it is not displayed.
Same happens when i use the code to embed the slideshow in a post.
Unfortunately i'm developing the site locally and can't show you. I could try to find a host to show you if you haven't got any idea about this.
