Embedded vs. linked images?
Commercial e-mail messages often contain images, graphics and other design elements. When a message is sent in the HTML format, images used in the message body can be either linked or embedded.
How to embed or link to images.
Linked images
Linked images are not part of the message itself. They are usually hosted by the message sender and referenced in the message body via an <IMG> tag pointing to the sender's server, as follows:
| Code: | | <img src="http://www.emailsignature.eu/phpBB2/images/eMailSignature_300_pix.png" width="300" height="70" alt="eMailSignature Logo"> |
No risk of interception in antivirus filters.
Email file size is unchanged.
You can use Word as email editor without having Red X's issues (Outlook 2003 and earlier).
Supported in Outlook Web Access (OWA).
Not shown in receivers inbox by default (image blocking) How to unblock linked images here.
Cannot be viewed off-line.
Embedded images
Unlike linked images, embedded images are part of the message itself. An embedded image is also referenced in a message body using an <IMG> tag, but instead of a URL, an image identifier, or Content ID, is used, as follows:
| Code: | | <img src="cid:My-Image"> |
Shown in receivers inbox by default.
Can be viewed off-line.
Risk of interception in antivirus filters.
Email file size increases.
Red X is showing when Word is used as editor (Outlook 2003 and earlier).
Not supported in Outlook Web Access (OWA) and paper clip will appear when replying in OWA. |
