Seam Mail Inline Image Attachment

[toppac.toppac.gmail.com]

What is the best approach for attaching inline images? I thought from reading the docs I could attach an image using a String value but it doesnt seem to work. If I have to write a utility method to read the image into a byte array that is fine. Just looking for the best approach. I have the following

<m:attachment 
            value="/WEB-INF/img/mail/banner.PNG" 
            contentType="image/png"         
            status="banner" 
            disposition="inline" />

Which I then try to reference as

<img width="728" height="53" id="_x0000_i1025" src="cid:#{banner.contentId}"/>

But I get

I seemed to have found the problem myself. We had duplicate copies of DataHandler on the classpath. Removing them now attaches the images (had to remove the leading forward slash from the path) but the images are not showing inline still. In outlook I can see there are attachments and the headers are there

------=_Part_0_1847394.1236303054514
Content-Type: image/png; name=banner.PNG
Content-Transfer-Encoding: base64
Content-ID: <xxpwfbifexdxdxnywiys>
Content-Disposition: inline; filename=banner.PNG

------=_Part_0_1847394.1236303054514
Content-Type: image/png; name=footer.PNG
Content-Transfer-Encoding: base64
Content-ID: <hzhmmocssxypaegtdodj>
Content-Disposition: inline; filename=footer.PNG

The content IDs match what is in the message source

<img id="_x0000_i1025" height="51" src="cid:xxpwfbifexdxdxnywiys" width="700" />
<img id="_x0000_i1034" height="26" src="cid:hzhmmocssxypaegtdodj" width="700" border="0" />

But they still are not showing. Any suggestions?

Was able to resolve this issue as well. Our ant build was corrupting the images in the packaging process by doing a copy with filtering. I had to do a separate copy command with filter off for the images. Everything seems to work now.
