Changed the test case to get it inline with the intended behavior 

The expected results match because the Render Image will return a size with the alternate content. The test case had an additional "/" in the file path, which lead to a failed load, whereas the Author intention was to to load it (I guess!).

Found this when I was going through some regressions. I will submit a patch if
my observations are valid.

The change looks reaonsable.  Do you need expectation updates?  I don't see any
changes to an -expected.txt or TestExpectations.

There is no change in the expected results. I have explained that in the
description, that the test case matches the expected result as the size returned
for the image is non-zero in this case.
