Add Image in Email From field

Question

In odoo 13 i have a field example:

birthday_picture = fields.Image(string='Birthday Picture')

i want to add birthday_picture image to be added in email template also which i declared in xml, i have added <img> tag and added still the image is not reflecting below i have shared the line

<div>
    <img src="${'/birthday_picture.png=%s' % object.birthday_picture}" style="width: 60px; height: 60px"/><br/>
</div>

please let me know where i am doing wrong

Answer 1

Actually i have added this:

<p>
    <img src="/web/image/birthday.reminder/${object.id}/birthday_picture/"/>
</p>

which doesnot reflect the image in template but when i looked for undelivered email from techncal > email. by removing force_send from code i can see my image reflected on it.

however i already searched that the email doesnot support base64 images but there is a tweak to do it as well. here is the link which descried the tweak
