问题 I asked about this before, but, I decided to start a new thread with a SCCE, it compiles sucessfully but it doesn't insert the image. Can anyone troubleshoot as to why it does this? Thanks, Chris.

问题 I swear I've looked everywhere and have been googling for hours.

问题 I'm having massive issues packaging my java program which contains images into a jar for conversion into and executable file. The images have been used in the background of the program and buttons. Please see the diagram below which shows the program I desire to convert to a jar. IMAGE As you see above the program runs OK. I created the same program with no custom background and custom buttons containing no images and I successfully packaged it into a jar and subsequently into an .exe file.
