l.frankline,
A couple of things, Firstly are you using sendmail to send email? Take a look at the
MIME::Lite documentation regards the default settings and configuration:
"On Unix systems (at least), the default setting is equivalent to:
MIME::Lite->send("sendmail", "/usr/lib/sendmail -t -oi -oem");"
Also the html content of your message assumes the recipient has a file called C:\temp\tendul1.jpg.
