Creating an Image Icon from a local file for eclipse

So I am trying to add an image to a JLabel object which is added to a JPanel called "topPanel" which is part of a JFrame called
"primaryWindow". I have already declared the "topPanel" and "primaryWindow". I found on other forms that you have to create a separate source folder and add the image file in that folder in order to access it and I did so.
However, when I execute the following, the image does not appear to be on the Label. I know that it has nothing to do with adding the JLabel to the panel properly because when I enter a String into the JLabel constructor, the String appears on the panel. An image however does not appear. Am I properly adding the image? I am using a mac if this helps.
private JLabel image = new JLabel();
image.setIcon(new ImageIcon("Check.png"));
topPanel.add(image);
primaryWindow.add(topPanel, BorderLayout.NORTH);

You can also use BufferedImage
BufferedImage myPicture = ImageIO.read(new File("C:\\xx\\xxx\\Check.png.jpg"));
Image scaled = myPicture.getScaledInstance(100,70,Image.SCALE_SMOOTH);
image = new JLabel(new ImageIcon(scaled));
topPanel.add(image);
primaryWindow.add(topPanel, BorderLayout.NORTH);
Note that "C:\\xx\\xxx\\Check.png.jpg" is the path where you save Check.png.
Hope this helped.

The ImageIcon that you passed into the setIcon method of the JLabel could be null. Have you tried to check if it is null before calling setIcon? If you create a "res" resource folder in the root directory of your project, you could try the following:
image.setIcon(new ImageIcon(ImageIO.read(new File("res/Check.png"))));
Additionally, if you are using Eclipse, you should try and refresh the project directory by right clicking and pressing refresh; sometimes Eclipse doesn't register files added.
Lastly, try setting the background of the JPanel to a certain color to see if it is displaying it and make sure its width and height are not 0 (it is possible that the layout you are using changed its size).

Adding few images in Java JFrame

I'm making 2D game. I have background and character images. Both of them are .gif files. What layout or something do I need to use to set background behind the character? I tried some ways but either they're in a row or nothing happens.
I am adding pictures like that:
URL url = Main.class.getResource("images/main.gif");
ImageIcon imageIcon = new ImageIcon(url);
JLabel background = new JLabel(imageIcon);

Code for Background :
first of all copy your background image and paste in src of code
than set layout to borderlayout like this:
setLayout(new BorderLayout());
now add this code:
setContentPane(new JLabel new ImageIcon(getClass().getResource("image.jpg"))));
Note: add your image name here "image.jpg"
now set layout to flow layout like this
setLayout(new FlowLayout());
and write your code here

Inserting an image as a label in java

label_007= new JLabel("My Label");
In lieu of the above Label, My Label I want to insert an image in the same position. How can I do that? I am just a novice in Java. Please help

ImageIcon icon = new ImageIcon('image.png');
JLabel image = new JLabel();
image.setIcon(icon);
The above code should work.
Make an image icon with an image file
Make a JLabel
Then set your JLabel's Icon

You can use ImageIcon for images:
ImageIcon ICON = new ImageIcon(URLClassLoader.class.getResource(IMAGE_PATH));
JLabel imageLabel = new JLabel();
imageLabel.setIcon(ICON);
URLClassLoader.class.getResource is using for packaging the application in runnable-jar file.
The IMAGE_PATH is relative to your project folders/packages. for example if the image is in com.app.images package, the path will be /com/app/images/image.png.
If you're novice in Java and particularly in Swing, I encourage you to check my swing projects- Minesweeper and Pacman. They are well-documented, I built them when I learned Swing.
Good luck :)

Simple Java GUI, cards not appearing

import javax.swing.*;
public class SlideShow {
JFrame slide = new JFrame("Slide Show");
public SlideShow(){
slide.setSize(300,400);
slide.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
slide.setVisible(true);
slide.setLocationRelativeTo(null);
JPanel panel = new JPanel();
JLabel label = new JLabel(new ImageIcon("Images/picture1"));
panel.add(label);
slide.add(panel);
}
public static void main(String[] args){
SlideShow slide = new SlideShow();
}
}
I have to create a simple Java GUI that displays some cards. First, I just wanted to test it by displaying one card. For some reason I can't seem to figure out why nothing is being displayed.

You haven't actually used a proper file name "Images/picture1". Should be something like "Images/picture1.png" with the file format
Also image files, generally should be read from the class path, if you plan on having them embedded to the program. To do so, you will first need to put the file in the class path. With most IDE build configurations it's as simple as placing the image in the src. So
ProjectRoot
src
images
picture1.png
Then you would read it like
new ImageIcon(getClass().getResource("/images/picture1.png"));
A better approach would be to use ImageIO.read(). If the file path is incorrect, it will throw an exception, so you know where you're going wrong
Image image = ImageIO.read(getClass().getResource("/images/picture1.png"));
ImageIcon icon = new ImageIcon(image);
You will need to put it in the try/catch block
Also do what codeNinja said about the setVisible() after adding component. Also preferably pack() the frame, instead of setSize()

You need to set the Frame visible after you add all necessary components to it. Move slide.setVisible(true); Down to the bottom of the constructor like this:
...
slide.add(panel);
slide.setVisible(true);
Alternatively you can add slide.revalidate(); at the bottom of your constructor.

How to change java icon in a JFrame

Ok so I've been researching this one quiet a bit. I am fairly new to java but thought that this one would be easy. Ive tried just about every way that has been answered on this site and still no luck, and usually when I look here I am able to find a answer that fits what I am looking for. Does anyone know how to change the Java icon in the top corner of the JFrame. I'm pretty positive that its not my file path either because all my images are in the same folder and they all work, this is the only one that I can't seem to get to work.
This is the first part my code for the main menu of my program, everything works except when i try to add the icon image. The code I've entered below does not have anything in it for the JFrame IconImage, I removed it since it didn't work. So if there is someone who knows how to get it working with this code that would be highly appreciated, thank you very much in advanced!
public class MainFrame
{
private MyPanel main;
private MyPanel2 create;
private MyPanel3 update;
private MyPanel4 find;
JFrame frame = new JFrame("Main Menu:");
public void displayGUI()
{
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel contentPane = new JPanel();
contentPane.setBorder(BorderFactory.createEmptyBorder(0, 0, 0, 0));
contentPane.setLayout(new CardLayout());
main = new MyPanel(contentPane, this);
create = new MyPanel2(contentPane);
update = new MyPanel3(contentPane);
find = new MyPanel4(contentPane);
contentPane.add(main, "Main Menu");
contentPane.add(create, "Create Part");
contentPane.add(update, "Update Part");
contentPane.add(find, "Find Part");
frame.setLocation(200, 200);
frame.setSize(700, 580);
frame.setContentPane(contentPane);
frame.setVisible(true);
}

I have an answer for you. First, make sure that the images are in a folder, not a package. Next, insert this line of code:
Image image = Toolkit.getDefaultToolkit().getImage(getClass().getResource("path/to/image.png"));
ImageIcon icon = new ImageIcon( );
setIconImage(icon.getImage());
This code gets the image from the class path, and returns it as a image icon, and then it sets it. This should add the image icon to the application. If it doesn't, then tell me.
EDIT: After you told me that that didn't work then I decided to take a second crack at it...
First, put your images into a completely separate folder. I usually call this /res. Next, put your image in there. Now, for loading I took a completely different route. I decided to use ImageIO instead of default loading. To load the image, you use this code:
try {
frame.setIconImage(ImageIO.read(new File("res/icon.png")));
}
catch (IOException exc) {
exc.printStackTrace();
}
ImageIO works a lot better for loading images. If this still doesn't work then please tell me.
If you want to export this as a JAR then put a folder the same name as you used in the program in the same directory as the JAR.

For example in a NetBeans project, create a resources folder in the src folder.
Put your images (jpg, ...) in there.
Whether you use ImageIO or Toolkit (including getResource),
you must include a leading / in your path to the image file:
Image image = Toolkit.getDefaultToolkit().getImage(getClass().getResource("/resources/agfa_icon.jpg"));
setIconImage(image);
If this code is inside your JFrame class, the image is added to the frame as an icon in your title bar.

This works pretty fine for me.
Just add this after you've created your JFrame.
try {
Image image = new ImageIcon("/icons/image.jpg").getImage();
frame.setIconImage(image);
}catch(Exception e){
System.out.println("Application icon not found");
}

Paste your image icon (fav.png) in the same package first,
Write following code in constructor of JFrame:
setIconImage(Toolkit.getDefaultToolkit().getImage(getClass().getResource("fav.png")));
Note:- fav.png is the name of icon

this.setIconImage(new ImageIcon(getClass().getResource("/iconsfolder/iconsname.jpg")).getImage());
// sets the Global icon for the system
try this code put after this code:
public void displayGUI()
{
