### Weird error when trying to embed images in problems.

Images were working before but something changed to make them not work now.
I get errors like the following when I try to view a problem with an image...
------
The macro alias cannot create a link from |/opt/webwork/webwork2/htdocs/tmp/AP_Physics_1/img/cc964cea-666d-346c-b3b7-005b8b36f097___b7efa9d7-83fe-39e8-b78c-bca83fce5daa.jpg| to |/opt/webwork/courses/AP_Physics_1/templates/Library/webwork_custom/problems/test_directory/test.jpg|.

------
The macro alias was unable to form a URL for some auxiliary file used in this problem.

In my Apache error log I see this..

Use of uninitialized value $imageURL in concatenation (.) or string at (eval 2431) line 2569. Here is the problem file.. DOCUMENT(); loadMacros( "MathObjects.pl", "PGstandard.pl", "PGML.pl", "PGcourse.pl", "parserNumberWithUnits.pl", "contextArbitraryString.pl", "parserMultiAnswer.pl", "parserPopUp.pl", ); TEXT(beginproblem());$showPartialCorrectAnswers = 1;
