Xml images not dislaying when site is viewed on server

I’m loading several images via an xml file. When viewing the swf locally (Flash preview or embedded in html in a browser) everything displays perfectly.

However, once uploaded to any server (I’ve tried several) some of the images don’t display. It seems very random, some display, some don’t. In one instance the image appears briefly then disappears, so I know it is parsing the xml correctly and the image is getting into Flash, then something is causing it not to display.

Is this some known Flash bug? has anyone experienced this before and have a solution?
