Image Grid with images that don't form a square or rectangle?

Well I have made a grid of pngs with equal dimensions that each image in the grid is the same dimension width and height as the next image the grid has 3 col and 3 rows number of images are 8.
So the bottom right square is showing as a white box in the image grid on the PC.
How do I handle that part should I manually crop it before using it in the jar or leave it as it is and do some kind of software handling for that.

I didn't really get your question...

BTW was it you on the sun forum a few day ago?

dont worry about that left over portion in your image it will be easily handled using GAME api yeah ofcourse it will create a liittle more jar size
