Make label with any image (gif and other)

What I want to do is:
Load an image that it is a gif, jpeg etc ... coming from a URL (but it is only the gif that I do not arrive but it must work with the others)
Put it in a JLabel in IconImage (although it suits me if it is not in the icon of the label as long as it is in the label)
Make it auto resize by taking all the space of the label but keeping its ratio
And finaly make this.add (label)
I already managed to do it with any type of image but the gifs was freeze to the first image
I searched for more solutions but could not find any that worked for me.
So, if someone could help me from the very beginning. I have the URLs and can share, if required.
Exemple of my code
//that work but images is not resize
JLabel label = new JLabel();
label.setIcon(new ImageIcon(new URL(image.getPath())));
this.add(label);
//images don't appear
URL url = new URL(image.getPath());
JLabel label = new JLabel();
java.awt.Image img = Toolkit.getDefaultToolkit().getImage(url);
img = this.scaleImage(img,Toolkit.getDefaultToolkit().getScreenSize().width/6); label.setIcon(new ImageIcon(img));

Try this, you may need to put it in a try-catch
BufferedImage image = ImageIO.read(new URL(url));
JLabel label = new JLabel(new ImageIcon(image));

Error when I try to put an ImageIcon in Java

I tried to put a simple icon in a JPanel formatted with the BoxLayout.
JPanel panel_4 = new JPanel();
contentPane.add(panel_4, BorderLayout.CENTER);
panel_4.setLayout(new BoxLayout(panel_4, BoxLayout.X_AXIS));
ImageIcon seven= new ImageIcon("‪C:\\Users\\alewe\\workspace\\SlotMachine\\Lucky_Seven-128.png");
JLabel lblNewLabel_1 = new JLabel(seven);
panel_4.add(lblNewLabel_1);
When I ran the code it gave me the error "Some characters cannot be mapped using "Cp1252" character encoding", I saved by UTF-8, now it starts but I can't see the icon.

Maybe if you use setIcon will help you:
ImageIcon seven= new ImageIcon("‪C:\\Users\\alewe\\workspace\\SlotMachine\\Lucky_Seven-128.png");
JLabel lblNewLabel_1 = new JLabel();
//Set your icon to your label
lblNewLabel_1.setIcon(seven);
panel_4.add(lblNewLabel_1);
You can read more about icons here

you will need a inputstream to read the picture. use it like this:
File f = new File("filepath");
InputStream in=new FileInputStream(f);
if (in != null) {
ImageIcon imageIcon = new ImageIcon(ImageIO.read(in));
label.setIcon(imageIcon);
} else {
LOG.debug("No icon found...");
}

how to add image from spectified package into label, frames etc

I have images i want to add in the following folder: G:\my java\DesktopApplication1\build\classes\desktopapplication1\resources.
How to go about adding image in this folder to my labels or frames?

Once built, the image will typically be inside a Jar. The resources in a Jar can be accessed a number of ways, here is one.
URL urlToImage = this.getClass().getResource(
"/desktopapplication1/resources/the.png");
ImageIcon imageIcon = new ImageIcon(urlToImage);
JLabel ...

You can do something like this:
ImageIcon image = new ImageIcon("path_to_image");
JLabel label = new JLabel(image);

I did something like this:
JLabel l2=new JLabel("");
try {
Image img = ImageIO.read(getClass().getResource("resources/wait20.gif"));
l2.setIcon(new ImageIcon(img));
}
catch (IOException ex) {
}
It does work, but i would have liked it more had the GIF animation was displayed. Nevertheless, if a static image is to be displayed, this is the way to do it.

how to put Image on JPanel using Netbeans

And how do I put Image on a JPanel using Netbeans?

Have a look at this tutorial: Handling Images in a Java GUI Application
At the same time you could code as well:
JPanel panel = new JPanel();
ImageIcon icon = new ImageIcon("image.jpg");
JLabel label = new JLabel();
label.setIcon(icon);
panel.add(label);

You can use ImageIcon and JLabel:
ImageIcon icon = createImageIcon("image.gif", "sample image");
// Label with text and icon
JLabel label1 = new JLabel("Image and Text", icon, JLabel.CENTER);
// Label with icon only
JLabel label2 = new JLabel(icon);
// Add to your JPanel
panel.add(label1);
panel.add(label2);

1) First Paste the image to the Application folder
2) Add a label to the panel
3) Right click label-> Properties
4) Select Icon-> more option
5) Select Package and File and Click oK
6) U R DONE :)

You have to set a JLabel with your icon property set to the picture.

There's even a video how to do it there in case you need it.

Displaying jpg image on JPanel

How can I display jpg image which I stored in arraylist in JPanel?
Im not able to display the jpg files in the JPanel.
String[] pictureFile = {"A.jpg","B.jpg","C.jpg"};
List<String> picList1 = Arrays.asList(pictureFile);
Collections.shuffle(picList1);
ImageIcon icon = new ImageIcon("picList1.get(0)");
JLabel label1 = new JLabel();
label1.setIcon(icon);
JPanel panel = newJPanel;
panel.add(label);

You should not put the call to the array in quotes.
Instead, you should try the following:
ImageIcon icon = new ImageIcon(picList1.get(0));

The problem is in the line
ImageIcon icon = new ImageIcon("picList1.get(0)");
It's interpreting the string as a file name. You should just need to unquote the picList1.get(0) bit.
