OK, so I had an issue where my images weren't showing when the .jar file was run.
Fixed that by using a fix from robberman I think his tag was.
Anyways once I fixed that by getting the images from getResourceAsStream etc it worked fine. So when creating the background image, a JLabel with an image, and JButtons with images as new components, this works great!
Problem I keep running into now is I have 3 buttons that need to change their icons in certain situations. I've tested this and it works without the NullPointerException in my test class, but when I try this in my projects class I get a NullPointerException each time it tries to setIcon.
Here's the method I setup to change the Icon. (I've tried this many different ways, and thought this would be easiest to see since it happens no matter what I do. ) Here's the constructor, the createGUI and the method to change the icons. Please help me out figuring what I'm doing wrong.

As you see from the above code, the createGUI where I create the buttons using getResource() etc works fine, it's the setImagesOnButton() method at the bottom that's giving me fits.
I tried also to include the places where the method is called to make it more clear. Also the println's in the setImagesOnButton all print out that the file is found and exists, then in the next line a NullPointerException comes up saying it doesn't exist? Confusing to me.
OK, I figured out what was going on. Three things to fix this. First of all, I realized that the null problem was not the icon I was trying to put on the button, it was a misplaced JButton call at the top in the CreateGUI method. I removed that (since I had it already created in the constructor) and that went away. Second I got rid of the stupd method cause it kept confusing me. (the setImageOnButton) and finally I found that if I put the images directory in the root of the package, then called for the images using new ImageIcon(Image.read(getClass().getClassLoader().getResourceAsStream("images/imagename.png"))); I could find it since I was relating it to the package rather than the class, it worked like a charm! I compiled, jarred it up and tested on my wifes' computer and it worked perfect! Thank you all for the help, Couldn't have done it without all the great info! and to say the least, I completely understand resources and how to put them in an application and use them now. :)
