606 # Revision 1.27 2006/10/08 17:00:51 fabiankeil
607 # Modified webbugs filter to create a comment around the offending
608 # image instead of removing it entirely.
610 # Adjusted regex to only match if there's at least one whitespace
611 # before the width and height attributes. Makes it more likely that
612 # they are indeed attributes, and not part of the value of another attribute.
615 # Thanks to Martin Thomas for diagnosing the cause of the problem.
