How to use images in email template in salesforce?

Hi Tanu,

You can include images or logos on your HTML and Visualforce email templates.

When creating custom HTML or Visualforce templates, simply include img tags that reference the image.

For example, for HTML:

<img src="https://yourInstance.salesforce.com/servlet/servlet.ImageServer?
id=015D0000000Dpwc&oid=00DD0000000FHaG&lastMod=1270576568000" alt="Company Logo"
height="64" width="64"/>

Visualforce example:

<apex:image id="Logo" value="https://yourInstance.salesforce.com/servlet/servlet.ImageServer?
id=015D0000000Dpwc&oid=00DD0000000FHaG&lastMod=127057656800"
height="64" width="64"/>

Hope this helps you.

Thanks
