Image In Signature Loses Url

hi

how can i link to images in a .htm signature file?

whether i link to an image on my local hard-drive, or on a web-server, the
image comes up blank when i insert the signature.

here's my signature html:

<DIV><FONT size=2 face=Candara>Thanks &amp; Regards,<BR>John<BR>President
&amp; Instructor<BR>www.xyz.net<BR>123-123-1234</FONT></DIV>
<DIV><FONT size=2 face=Candara></FONT>&nbsp;</DIV><DIV><FONT size=2
face=Candara><IMG
src="http://uploadingit.com/files/1097416_19tzt/laptopsmall.gif"
width="96px"></FONT></DIV>

thanks
