Hello Alexander,

A few comments.

1) Lines 53,59: By convention it is better to put constants in upper case, 
e.g., NUM_IMAGES and BLACK_SIZE.

2) Line 45, 102: The test references the internal package 
com.sun.imageio.plugins.tiff. In general it is better to use the public 
packages.

3) Line 69: If the test fails, it would be good to know the random seed. It 
would also be good to be able to set the seed when running the test. The 
approach taken in core libraries may be seen in 
test/java/math/BigInteger/BigIntegerTest.java. The 
jdk.testlibrary.RandomFactory class is used to create the Random instance and 
to obtain any seed provided via Java properties. This requires the test tags 
“@library /lib/testlibrary” and “@build jdk.testlibrary.*” and it is also good 
to add “@key randomness.” 

Regards,

Brian
