i can't find nothing obvious about inline image problems with gmail so i wondered if any of you guys have come across this problem and what i could do to solve it.

 

 

here is my headers and boundarys set for the email...

Content-Type: multipart/related; boundary="e3b811c438657c9d0f9ae45330038d29"

According to the specification the content-id is supposed to follow the addr-spec format which is defined as addr-spec = local-part "@" domain. Examples I can find in my email seem to follow that pattern, so I'd suggest you try the same.

 

i tried what you said kicken and still have no joy...i also tried cid:logo@mydomain.co.uk

 

here is my altered code

 [7] => SUBJECT: test email
    [8] => FROM: mydomain.co.uk<****>
    [9] => TO: *****
    [10] => MIME-Version: 1.0
    [11] => Organization: mydomain.co.uk
    [12] => X-Priority: 3
    [13] => X-Mailer: PHP7.0.10

any other suggestion would be great...i've looked a so much regarding embedded inline images and i can't see nothing else that i may be missing...i'm feeling there's something else that needs to be added to my headers though.

 

i even sent myself an email from my gmail account with an embedded image and tried to cross reference but all formats i saved we're barely readable.

 

thank you

i had a brain storm last night and sent the email via phpmailer and viewed what was actually being sent to the server...this format works perfectly now for alternative mail with embedded images.

Content-Type: multipart/alternative; boundary="fae15ab6820aee7cab838cf3b8f5ef37"
Content-Transfer-Encoding: 8bit

This is a multi-part message in MIME format.
--fae15ab6820aee7cab838cf3b8f5ef37
 Content-Type: text/plain; charset="utf-8"

plain email here
--fae15ab6820aee7cab838cf3b8f5ef37
Content-Type: multipart/related; boundary="aaf2651d4917027cd4c6a335082910a5"
--aaf2651d4917027cd4c6a335082910a5
Content-Type: text/html; charset="utf-8"

Sever: <span>here is our logo</span>
<img src="cid:logo.png@domain.co.uk" width="
