Granted that I fail to understand which is the perl question here, if you're using CGI.pm as you definitely should, and if you're using its header()'s default settings, then you're serving XHTML 1.0 Transitional; so I haven't the slightest idea whether this may have to do with the problem you're experiencing, but the above should be 
<!--
<img src="htdocs/test/DailyReport.jpg">
-->
<img src="htdocs/test/DailyReport.jpg" />

of course CGI.pm itself would take care of this as long as you 
print img { src => $DRurl, alt => "[Daily Report]" };

Update: fixed a typo according to dorward's reply.
