I have my classes in src default package Im not sure where I should add the images or if I have to add it to the build path or correct way of adding the images to the build path in the newest version of eclipse

Files in a Jar are not files in the sense of a file on disk. They are simply a (possibly) compressed stream of bytes.
Jar 中的文件不是磁盘文件意义上的文件。它们只是一个（可能）压缩的字节流。
Java makes it easy to extract these "resources" from Jar files through the use of the ClassLoader
Java 通过使用 ClassLoader
background = ImageIO.read(getClass().getResource("/wood.jpeg"));
Should work...
应该管用...
This will return a URLwhich ImageIOcan use to load the resource.
这将返回一个URL它ImageIO可以用来加载资源。
