Embedding Outlook 2013 signature images

Problem:

Images in signatures attached to emails in Outlook 2013 are visible when composing messages but not visible when opening emails in the recipients' inboxes.

Fig.1. A result of images not being embedded.

Checking email html body reveals that image was not embedded but linked:

Solution:

Microsoft changed the way Outlook works in terms of adding images to signatures. Images are not embedded but linked. Unfortunately, such images will not work unless the resource in which they are kept is a shared location. In most cases users keep signature images in local Outlook templates folders along with the signatures. Such folders are not shared by default. Also, when using CodeTwo Email Signatures images from signatures are stored in local templates folders.
