How to add image to jFrame?

Question

Java

Good afternoon everyone.
I have drawn a program interface in the NetBeans form designer. More specifically, a window similar to some "About" windows. Also I want to "fasten" a picture in this window. Tried with jLabel but it doesn't scale the image. And I need that when the window is resized, the image size also changes (not the window background, but a separate object, like jLabel, jTextArea, and other Swing objects).
I'm a beginner in NetBeans, and in Java too, so I'm sorry in advance if I ask stupid questions))
By the way, I read an article here Adding an image to a JFrame
Created a jPanel subclass, as written in the article, but did not understand how to declare it in my form. Because NetNeans won't let me insert a "foreign" object. Maybe somehow you need to configure NetBeans itself?

You write the code with pens, without forms! And how can you help without the code?
