Odoo Qweb Report to show image Google Drive hosted image
Sometimes, due to your Odoo server setting, you are not able to display the image in the Odoo Qweb Report.
A quick solution is to upload the image to the google drive (make sure you share to all), and display the google drive image link.
<img t-attf-src="https://drive.google.com/uc?export=view&id=118dn3fZi1DILRmocfqIXZWEc6PT-dNyk" height="100px" width="200px"/>
Note: You can also show the image in the Odoo email template with the google drive image.
