java - JPanel Wont Load Image -

so can't figure out why can't load image jpanel....the code kinda long, have commented, should simple deduce whats going on. can help? have tried removing background color , did not seem @ (other remove background color)

edit

i managed fix error drawscene method being called in class wasn't added to, , show there error loading image...i'm not entirely sure why though. image using if wants try running program themselves. have added in package right underneath window.java file.
