Photo Gallery Using XML and Flash

I am using Flash Professional 8. I made a Flash photo gallery driven by XML using the tutorial “”. When I publish it by pressing ctrl+enter or publish on web by pressing F12, everything is fine. I can see photographs, descriptions, and fully working buttons. But when I put my .swf clip to the website I am developing, nothing comes on it.

I am still testing these on my PC and yet to upload them on web.

Is it something to do with levels or something else? Please help me!
