RE: Witango-Talk: Images in HTML emails

[Ben Johansen]

Hi,

Ok, first you are going to have to find the program to convert the gif to
BASE64
then go to this link
http://www.zvon.org/tmRFC/RFC2557/Output/chapter9.html
and go to
9.5. Example using CID URL and Content-ID header to an embedded GIF picture
you are going to have to get real good at
Boundaries
and
Content-type

in the mail action you are going to have to put the initial
sample:
      Mime-Version: 1.0
      Content-Type: multipart/related; boundary="boundary-example";
              type="text/html"
in the custom header lines
and then in the body you are going to have to place the
html with the <image src="cid: within one set of boundaries
and the result of the base64.exe on the gif
in the body with another set of boundaries

I have been meaning to do this as a test but since Witango 5 I can do this
with the new <@EMAIL Tags

Hope this helps some

Thanks for the responses, but so far they have really only muddied the
water.

I'm not interested in the stats, ethics, or efficiency of this practice. I'm
not even sure if it is any benefit to the particular task at hand. It's more
of a mountain that I intend to climb because it's there.

What I've discovered so far is that references to attached images in HTML
emails are of the form <img src="cid:image.gif";> but image.gif is not the
name of the image (although it could be) but is the Content ID.

In Perl and PHP solutions you specify a Content ID for each graphic, then
call this ID in the HTML. So if you had an image called 'image.gif' you
would specify that it's CID is 'image.gif' (or ABC or whatever) and then
refer to it in the HTML as <img src="cid:image.gif";> (or <img
src="cid:ABC";>).

Unforunately the Tango Mail action doesn't provide a CID specification field
for attached items.

So is anyone actually doing this? If so, how? With a fourth party email app
perhaps? No reason why Tango couldn't pass the info to a CGI that does
support Content ID specification.
