[CS3] Problems Loading Images From External Urls Into Flash Movie

Hi All,

I created a continually scrolling horizontal panel of images which are loaded via XML from an external server.

However i get strange results when im playing the movie. Sometimes all the images load without a problem but occasionally the loading process will stop on one image and cause the movie to stop working.

Because i load all of the images into the flash movie first, this means that the movie never shows any images.

Does any one have any idea whay externally hosted images may not load correctly?

My code is the following:


PHP Code:
