2.    Watch memory be consumed.


What is the expected result?
-------------------------------------------------
Every image should be loaded. Each image object’s data should be cleaned up after is goes out of scope. 

What happens instead?
-------------------------------------------------
All memory is used. Image data does not appear to be freed after it goes out scope. Browser crashes and a low memory crash log is produced.
