Dynamic loaded img not working here is the code

For some reason the images ( except for one) are not loading. they all are the same file type. no dynamic jpgs all baseline. the one image that is even close to working looks just like bands of colors. here is the code in the first frame. the rest is the same. please help. Could it be that i need a preloader?

picture.loadMovie(“images/img1.jpg”);

loadText = new LoadVars();
loadText.load(“text6.txt”);
loadText.onLoad = function() {
newsbox.text = this.newsbox;
};

thumbb1.onPress = function () {
gotoAndplay(65);

}

thumbb2.onPress = function () {
gotoAndplay(135);

}

thumbb3.onPress = function () {
gotoAndplay(207);

}

thumbb4.onPress = function () {
gotoAndplay(278);

}

thumbb5.onPress = function () {
gotoAndplay(349);

}

thumbb6.onPress = function () {
gotoAndplay(420);

}
