Photo Slideshow with XML - Image gap on first cylce through slideshow


I am new to this site, and I went through the tutorial on this site, "Photo slideshow using XMl and Flash, "
but I encountered a problem where my images lag the first time they cycle through all the images in the XML file.

The first time the flash page loads and starts the slideshow, I don’t want the gap between the transitioning of the images where the movie backgound shows. I think it has something to do with the images loading for the first time, so I tried to load each picture in a different movieclip with an alpha of 0 before the slideshows starts, but it didn’t work and there is still the gap between the images the first time the pictures cycle through the slide show.

Please offer any advice on how to stop the image lag the first time the slideshow cycle through all the images in the XML file.
