Your only problem is how you bring in the images. Its saying that when it looks for the image at the specified location, nothing(null) is found.

you might want to try

ImageIcon ii = new ImageIcon("pociu/games/chess/" pieceName ".png"); //makes ImageIcon

ii.getImage(); //returns image

that should make it for you, without the Stream problems. other than that the code is pretty good.

if you wouldnt mind, could i borrow your chess piece images? i need to find some for a similar program i am doing.

If the program does not work without the pictures, why then you did not put the picture somewhere online ? why should the people try and try but in vain, the time is expensive.

i liked...i think its will be enough for waht i am trying to do
anyway.... i just changed the line with problem to:
InputStream inIcon = ClassLoader.getSystemResourceAsStream("aaa.png")
the file aaa.png is a cartoon i did in paint brush just for testing the code...
it worked fine
