The way native libraries work in Java is usually that you must call some sort of cleanup method manually. The garbage collector will clean up java objects, but not memory from native libraries and as you know, C(++) does not have a garbage collector.

(there must be a good reason that wpilib isn't using finalize() to call free() - maybe finalize is unreliable?)

Anyway, I have to go with the previously stated recommendation, that you reuse the same image object. NI vision allows you to do that.
