That would almost work, provided you'd send the correct headers:
#!/usr/bin/perl -wT
use strict;
use CGI ':all';
my $q = new CGI;
my $imagedir = "/path/to/images";
my $file = $q->path_info();
$file =~ s!^.*/!!gi;
print header("image/jpeg"),
do { local *ARGV; @ARGV = "$imagedir/$file"; <> };
Be sure to use taint checking on your path info, as you wouldn't want anyone to view files they shouldn't be viewing... :)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
