O365 access token: image not loading until login in actual SP

[praveen rengarajan]

Authenticating the user using O365 API, using that token again am getting SharePoint resource token.There is no problem until here.

https://xx.sharepoint.com/sites/SC/_api/web/lists/getByTitle(\'Announcements\')/items/?$orderby=Published_x0020_Date desc

Able to get entire list and column data. But, the actual problem is, the image in the body content is not displaying until I logged in SharePoint site in the same browser. Why? It's unable to get resource files from SharePoint using O365 SharePoint access token.

The token would work o2f you requested the image using the api. But the browser performs log in via a cookie.

Do users log into the location where your code runs? If your app uses AAD for auth, the user should have a cookie.
