Put the image you want on your computer's desktop. This can be a .JPG, .PNG, .GIF or .BMP file. I would highlydiscourage BMP files because of their size.
Drag the image file into Eclipse and drop it onto your project folder. This has an icon next to it that looks like a folder and has a small 'J' on it.
Place the method (below these instructions) inside your Java program. DO NOT put it inside another method. It should be in the class. It is a method which means it should be pasted at the class level. Still unsure? Find your playGame method and paste it above the playGame method, but after the makeProgramWait method ends.
In your constructor or newGame method, add the following line: 'image = readImage("mortland.jpg");'
In your paintScreen method, add the following line: 'g.drawImage(image, <x>, <y>);' where <x> is the x-Coordinate and <y> is the y-Coordinate of the top left corner of the image you want to display.
