[QUOTE="beanbrown, post: 4504795"]
I have been wholely unsuccessful in having an inline image attachment
show in an HTML email.  I have been able to create an email with plain,
html and image parts, but when attempting to set the content-id for an
image (so that I can refer back to it in the HTML), I am unable to get
it to appear using the headers attribute of the attachment.

Here is my code:
class Mailer < ActionMailer::Base

def email_html( user, to, subject, message )
@recipients   = "[email]hello@world.com[/email]"
@from         = user.emailaddr
@subject      = subject

part :content_type => "text/html",
:body => "<b>Welcome to <img src=\"cid:img1\" border=1>!</b>"

part "text/plain" do |p|
p.body = "this is plain"
p.transfer_encoding = "base64"
end

attachment :content_type => "image/gif",
:headers => {'content-id' => 'img1'},
:body => File.read("c:\temp\logo.gif"),
:filename => "logo"

# this works
self.parts[self.parts.length-1].filename = 'foo'

# this does not work
self.parts[self.parts.length-1].headers['content-id'] = 'bar'

end

# Please help!
# Eric
