It really depends on which program is in control when you are trying to look up /images/image.png. Sometimes /images/image.png is a URL, and sometimes it is a file path, and the two are most definately different, even though they look the same.
<P>
Apache handles this internally, using a complex set of rules. /cgi-bin/ is one of these rules. Instead of looking in /var/www/cgi-bin/, Apache looks in /usr/lib/cgi-bin/ (under Debian). /images/ can be remapped in Apache too, perhaps leading to /var/images or something like that.
<P>
However once your perl script has started, path lookups are handled as normal Unix path lookups (using the system PATH variable, plus any changes depending on the users settings).
<P>
This is confusing, difficult, undocumented and something you have to learn when dealing with Unix. Or any operating system really. Web services are a confusing mash of programs, and figuring out which one has control at the critical moment is a big part of figuring out the bugs.
