Loading Images from a website taking forever.

Hi there, I have a list of images I am loading from a website, these images are all around 5kb each.  When I perform a load, it seems like it takes seconds to load each image.  How can I load them properly so it will load faster?  This is basically what I am doing now.  I am populating a JList with icons and text.  The mFilename_ac variable looks like "http://www.website/picture/picture.gif".  So how can I ensure the picture loads, and that it loads fast?  I have put it in a thread, but it takes 60 seconds to load 100 images on a highspeed dsl?  Thanks experts.

            DefaultListModel dlm2 = new DefaultListModel();
            URL image = new URL(mEmoticonData_t[i].mFileName_ac.toString());
            ImageIcon myIcon_t = new ImageIcon(image);
            for (int i=0; i< numImages_i; i++)
            {
                    dlm2.addElement(new ListEntry(mEmoticonData_t[i].mCharacters_ac.toString(), myIcon_t));
            }
            emoticonList.setModel(dlm2);

The second statement seems to suggest its more like 0.5 sec per image.

Can't see anything in the code that would cause it to be unnecessarily slow.

If you don't use an ImageIcon and instead load your images directly (as Image's) then they will load asynchronously.

ImageIcon icon = ImageIcon(new URL("http://www.mysite.com/myimage.jpg"))
Image image = icon.getImage();

Make sure it *is* the download that's taking longer than you think it is, and not the rendering, before you try to take remedial action. For that, you'd be better leaving the code as it is (synchronous) first. You can then give objects' suggestion a try later, although it may not improve things and may even slow them down.

Can I load the images from my .jar file or will I have to get it digitally signed?

Yes - why do you think you'd need to sign it?

Absolutely, use getResource() to get a URL for the image.
No need to sign it.

URL image = getClass().getResource("/images/my.gif");
ImageIcon i = new ImageIcon(image);

because it will greatly speed up the loading ???

Using getResource will have no effect on the loading speed whatever
