I have a very big image but I want to resize it inside jLabel in Netbeans using jLabel properties. Please help me if possible.
You can use the Image.getScaledInstance(...) method to scale the image to your desired size.
Then you create an ImageIcon using the image and add the Icon to the JLabel.
Edit:
You can also try using Darryl's Stretch Icon. Using this class the Icon will resize dynamically as frame resizes if you use an appropriate layout manager.

I have a frame with a border layout that includes a panel with a border layout at its center that has a label in its center that presents images.
Another thread is accessing that label to portray images that can be seen as a video - this works.
However, the frame itself is sized this way every time:

I have to resize it manually to show the image every time I run the program.
SetPreferredSize doesn't change or do anything to achieve what I want.
The code:

Is there any way to initiate the frame at a specific size before it gets the images?
You might be looking for .setMinimumSize instead. setPreferredSize does not provide constraints and can thus be changed by other components such as the container that is used to show the image.
I am using the drag and drop system of netbeans to create my GUI.
I created a button and added an icon to it, my problem is that the image is to big for the size I want the button to be.
Is there any way of making this icon having the same size as the button?

The size of the button is determined by the size of the Icon.
You can create a new Image by using the Image.getScaledInstance(...) method and then create an new ImageIcon from the scaled image.
Depending on your exact requirement and usage of layout managers, you might be able to use the Stretch Icon which will adjust the size of the image as the size of the button is changed.
I currently have a JDialog (class that implements JDialog and is constructed like a jframe), and has 3 swing buttons placed on it. Currently I have it set, undecorated = true, to hide the outer frame. Is there any way to use my image to replace the default square frame?
This is what I aim for :
The blue square with shadow is the pre made image.

Well, the best way would be to set the background of the panel and then add a ShadowBorder to the panel. This will provide you with far more flexibility in the future as you can create many panels with different colors and reuse the same ShadowBorder instead of having to create an Image every time. I don't have an example of a ShadowBorder, but you might find one if you search the web.

But if you really want to use your premade Image, then you can just:
create a JLabel and add your Image to the label as an Icon
add the label to the dialog
set the layout manager of the label
add your components to the label.
I need to create a custom GUI Component about same like shown in the following image.
it has some buttons and labels on this.
How can i create like this
You could use a JWindow, with an Image for the background picture. For the buttons, use a JButton with an ImageIcon.
You can have a JFrame with nullLayout then use a JLabel with the image.
Now for buttons use setContentAreaFilled(false) and setBorderPainted(false) to remove the default button style and it will look exactly like the image that you have passed while creating the button.
To position the Frame at the center use setLocationRelativeTo(null) .
I think that should solve your problem.
I'm using a JPanel containing a JLabel with an icon. I'm using a ComponentAdapter on the JLabel to request a correctly sized thumbnail from the controller (using MVC pattern) when the JLabel is resized. This works fine when the JLabel is resized to be bigger than before, so then it's filled with an ImageIcon the size of the JLabel. However, when resizing the window to be smaller, it simply doesn't resize the JLabel at all (because of the icon's size, I'm assuming).
Is there possibly some layout manager or setting to make the JLabel disregard its content (the ImageIcon) and resize itself anyways? I mean, it can truncate text, so it ought to be able to just show part of the image when resized smaller.
Try experimenting with setPreferredSize() and setMinimumSize() to ensure the JLabel is allowing itself to shrink to the required size. You also need to double-check what kind of LayoutManager you are using and what constraints, if any, you use when adding your component to the panel. Try a different layout manager if you can. If none of that works, you will need to provide some example code.
