Weird image problem

so i placed an image on the stage of my flash movie, a rather large jpeg image about 1.7mb and about 4200px wide. When i place it on the stage and align it to absolute left and top, and then press ctrl Enter to view it, it shows up fine. Now, when i center the image so that the center of the image is on the movie stage and the rest hangs off the edge of the stage, and then export the movie to test it, the image turns to a color spectrum. I’ve tried using jpeg and gif, does the same thing at 300dpi and 70dpi. Now, the weird part, as if that isn’t weird enough. When i zoom in on the exported flash movie with the spectrum, if i zoom in two times, i can see the pic zoomed in twice. Is that weird or am i missing something???
