Security Sandbox Violation? What

*** Security Sandbox Violation ***
Connection to “http://img3.freeimagehosting.net/uploads/9a1cfd70c3.jpg” halted - not permitted from [file:///C|/Documents%20and%20Settings/Administrator/My%20Documents/St.%20Louis%20Secondary%20School%20Graduation%20Dinner%200708/imageGallery.swf](file:///C|/Documents%20and%20Settings/Administrator/My%20Documents/St.%20Louis%20Secondary%20School%20Graduation%20Dinner%200708/imageGallery.swf)

I meet this when I try to import external images. How can I make the image available? In other words, how can I shut this thing down so that my image can be shown?
