How to add your badges to linkedin
The first way is to add a link.
In your Linkedin profile, select Add a section; from the dropdown go to Featured -Links. This one should pull the badge picture if you use the badge URL.
The second option is to Add a section- Background- Licenses and Certifications. This one will show the issuers logo as the display picture.
The third does not show a picture you can only add text. Add a section- Accomplishments- Honors and Awards.
