Unfortunately, if contents are lost you need to loop back to where you
create the image, which means you don't have enough code inside the
while loop. All of the items I mentioned below in my comment need to be
included in that "loop back around". To be painfully clear here, the
loop should look like this:
backgroundColor = ...; /* no need to create this inside the loop */
img = ...;
Graphics2D imgGraphics = img.createGraphics();
// fill img with transparency
} while (img.contentsLost());
The rest looked fine...
