Image will not display in a jFrame

Question

So, I had this working, but then I resized the jFrame and the image, and now it doesn't work. I even tried setting it back to the original size and it still doesn't work. I changed nothing else in the code.
I'm using Netbeans IDE and this is a java desktop application so maybe it changed something without telling me. Any advice would be appreciated.
ImageIcon bgmap = new ImageIcon("C:\\Users\\1\\Documents\\NetBeansProjects\\Timekeeper\\src\\timekeeper\\resources\\Sunlight.png");
Image i = bgmap.getImage();
ImageObserver Iob = null;
//Al.setBackground(Color.black);
//Al.setForeground(Color.black);
jPanel3.getGraphics().drawImage(i, 0, 0, Iob);
jPanel3.getGraphics().setPaintMode();

Make sure the image i is not null. Paint in a component's paintComponent() method (and unless there is some reason for doing so, don't keep recreating the image.)Added to that:
1) If you mean JFrame, spell it correctly (with correct capitalisation) so we can be sure you are dealing with a JFrame as opposed to some 3rd party class that nobody here knows about, nor supports.
2)
ImageIcon bgmap = new ImageIcon("C:\\Users\\1\\Documents\\NetBeansProjects\\Timekeeper\\src\\timekeeper\\resources\\Sunlight.png");
Image i = bgmap.getImage();
ImageObserver Iob = null;
//Al.setBackground(Color.black);
//Al.setForeground(Color.black);
jPanel3.getGraphics().drawImage(i, 0, 0, Iob);
jPanel3.getGraphics().setPaintMode();How can you jam so much crap into so few lines?
a) Try not to post code with lines that are commented out. That is just a waste of bandwidth.
b) Declaring an ImageObserver and setting it to null before passing the null variable to the drawImage() method is a waste of a line, since you could directly pass 'null'. But..
c) JPanels as well as many other components, implement an ImageObserver, so why the heck not pass the JPanel is ImageObserver, rather than 'null'?
d) If you do not pass an image to something that is an ImageObserver, ensure it is loaded by using a MediaTracker.
e) Never call getGraphics().
f) Your call to setPaintMode() at the end of the lines. What did you expect that to do? Did you read the JavaDocs for the method, or did you just throw it in there for 'good luck'?
In future, please consider posting code in the form of an SSCCE. For image based SSCCEs, you can hot-link to any of the [images at my site|http://pscode.org/media/#image].
