I am trying to embed a signature image into an email.  The image is created:

<cfoutput><cfsavecontent variable="content">#TicketSignature#</cfsavecontent></cfoutput>
<cfset Signature = ImageReadBase64(content) />
<cfimage name="thisSignature" source="#Signature#" action="read" >

When I "WritetoBrowser" the image appears fine.  All good so far.

In my Cfmail tag I use:

<cfmailparam file="signature.png" contentid="signature" content="#thisSignature#" disposition="inline" type="image/png" />
and
<img src="cid:signature"> to show the image.

My problem:  For some reason the image in the email is viewed as a negative image ... black background and light blue signature.  Somehow, the cfmailparam tag is converting the image.  Why???  I have tried everything I can think of, but nothing will change it back to white background and black signature.

Any thoughts would be very helpful.
