Need help with an applet that will only run as an application

Question

I am working on a slide show applet. The problem is that is won't run as an applet. I added a quite standard main method to stick the applet in a JFrame and this worked. I believe that the problem lies in how I am trying to open the files.
here are two of the methods that I believe contain part of the problem
     private void showImage( String image_name )
          image_file = Toolkit.getDefaultToolkit().getImage( image_name );
          display_image.loadImage( image_file );
          repaint();
     private void setFileFolder( String folder )
          file_finder = new File( folder );
          file_results = file_finder.list();
     }image_file is an object of class Image, display_image is an object of class ImageComponent (extends JComponent to draw an image), and file_finder and file_results are both objects of class File
I would greatly appreciate it if some one would help me with this.

Answer 1

Ok. I got the image loading to work.
Now how do I fix the second method shown in my first post? It is needed to find all of the images in one specific folder so that the slide show can run.
