Rails - Jan 2006 - Using image_tag in Action Mailer???

I''m trying to send a HTML formatted email with Action Mailer and 
everything works fine except for when I try to use a Rails image_tag in 
my email template.  Does anyone have experience doing this? I keep 
getting this error

|undefined method `request'' for #<SamplesDirectMailer:0x231d4d8>|

Extracted source (around line *#7*):

|7:   <div style="position:absolute; top:0px; right:0px;"><%=
image_tag "/images/ldc.jpg" %></div>|


I''ve also tried "../../images/ldc.jpg" and a few other paths
If I remove the image_tag I receive the email just fine.... and yes the 
image is in the /images dir

Thanks in advance for the help,
Chris
