send inline attachment image in html email (maybe a way to set cid: URL)
We have a repository that holds text for email as pure HTML. I have some code to send email with this text as the html body and that works well and is fairly simple. We can also add attachments.
What I haven't figured out how to do is embed and image in the email. From what I understand, the email would have in it a "cid:" URL like --
<img width="128" height="128" id="Picture_x0020_1" src="cid:image001.png@01CF6E9E.C4B30B30">I could compose a tag like that no problem. The issue is the cid: for the image. I know how to add attachments. And I know you can set the inline flag to true or false. What I can't see a way to do is set the id for an attachment I'm including (or get back an ID after attaching it) so I can then put that content id (cid:) in the URL in the HTML body.
It may be that the email and attachment classes in Apex are just not deep enough to perform this task. But if anyone know's a way to do it, feel free to post suggestions.
I
a. You embed the image as base-64 encoded string in your HTML email template/message
b. You assign a content-id to the block
c. You reference it in the IMG tag using the "cid" attribute.
Let me know if this helps at all.
Hi Ken - I just hit the same problem - did you find a workaround/solution? If only we had an Content-ID assigned!
@ Saurabh: Yes the embeded base-64 works fine in a web browser (except for IE7) but it just doesn't work in an Email browser, which is very frustrating.
a lot of email clients (gmail, yahoo + outlook) doesn't support base64
