Sample Image on the roboRIO cannot be found

[Team3205]

We get an error on the FRC DriverStation when we try to enable the robot and the code looks for the image on the roboRIO:

ERROR Unhandled exception java.lang.IndexOutofBoundsException at [java.nio.Buffer.checkIndex(Buffer.java:546), ...

called at line NIVision.imaqReadFile(frame, "/home/lvuser/SampleImage/image20.jpg");

The image is in that path on the roboRIO and we are writing in java any input would be greatly appreciated. Thanks in advance.
