function firstImage() {
    if (loaded == filesize) {
        picture._alpha = 0;
        picture.loadMovie(image[0], 1);

        //        desc_txt.text = Description_Array[p];
        name_txt.text = Name_Array[p];
        school_txt.text = School_Name_Array[p];

        picture_num();

        picture._x = (picture._width) / 2;
        picture._y = (picture._height) / 2 ;
        **desc_txt.text = picture._width + " " + picture._height;  **          
        }

    if (p<(total-1)) {
        p++;
        if (loaded == filesize) {
            picture._alpha = 0;

            picture._x = (600 - picture._width) / 2;
            picture._y = (400 - picture._height) / 2 ;
