Help, I can see my show in the preview, but when I upload/publish it is not on the page. I used the foreign object to place the flash holder. I have uploaded all the images, the media folder, don't know what else to try. Thanks

It depends on what kind of slideshow do you have. Some slideshows require additional files (i.e. xml) to be uploaded to the server and placed correctly in order to work. How did you create your slideshow and can you post a link to your page?
