How to embed images into signatures in Outlook 2013/2016

Problem:

You are not able to embed graphics in email signatures: images are visible when you compose an email in Outlook 2013 or 2016, but they are not displayed in the recipients' inbox (Fig. 1.).

If you check the email's source code, you can see that your image was not embedded but linked:

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">
  <span style="font-size:10.0pt;font-family:&quot;Arial&quot;,&quot;sans-serif&quot;">
  <img width="326" height="118" id="_x0000_i1025" src="file:///C:/Users/admin/AppData/Roaming/Microsoft/Signatures/Images/banner.png" name="_x0000_i1025"></span>
</p>

Solution:

Microsoft has changed the way Outlook adds images to signatures. In recent versions of Outlook, images are not embedded but linked. Unfortunately, linked images are not displayed unless the resource in which they are kept is a shared location. In most cases, users keep signature images in their local Outlook template folders along with the signatures. Such folders are not shared by default. The situation is the same in CodeTwo Email Signatures for Email Clients: signature images are also stored in local template folders.

To solve this issue, you can enable signature image embedding in Outlook by modifying your Windows registry.

Warning

Be aware that editing the Windows registry may be a risky operation. By doing it incorrectly, you can damage your operating system or lose your data. If you do not have any previous experience in using Windows Registry Editor, ask an IT professional to help you.

If you are aware of the consequences, follow the steps below to add a new key to your Windows registry:

  1. Open Windows Registry Editor (run regedit.exe via the Start menu).
  2. Open the following key:

    HKEY_CURRENT_USER\Software\Microsoft\Office\X.0\Outlook\Options\
    

    where X is the version of Outlook you are using.

    Be advised that Outlook 2016 is 16, but Outlook 2013 is 15 and not 13.

  3. Find the following subkey and open it (if it does not exist, create it):

    Mail
  4. Add a new value of the following type:

    DWORD (32-bit) Value
  5. Provide the name of the value exactly as below:

    Send Pictures With Document
  6. Modify (edit) the created value in the following way (see Fig. 2.):

    Value data: 1
    Base: Decimal
