Hello, Im openning this JPG image in the Flash using MovieClipLoader. Eventough
the image has the same size as the component I use to display it... It opens
bigger (so I cannot see most of it).

 loadPic("C:/map.jpg", "picMap");
 /*  Loader  */
 function loadPic(image, target) {
        var mcl = new MovieClipLoader();

        mcl.loadClip(image,target+".pic");

 }

what's the instance name of your target movieclip?  if it's picMap.pic, pass picMap (without quotes) to your target parameter in loadPic() and use target.pic in your loadClip() method.
