We're using the Chatter API and pulling a feed into our application.

We are retrieving the image URL from the Chatter API feed response and attempting to display it in the web app.  The detail from our HTTP XHR traffic analyzer is showing a 302 Found HTTP response but the following message is also showing and the profile photo of each user is missing,

Resource interpreted as Image but transferred with MIME type text/html: "https://na8.salesforce.com/content/session?url=https%3A%2F%2Fc.na8.content.force.com%2Fprofilephoto%2F729C0000000DXXXXX".

The login to the SFDC site/portal itself is timedout but we refresh the API token for the Chatter API calls and the photos don't show.

Can anyone offer an explanation for why this is happening? Or what the solution might be?
