I am trying to get the thumbnail for an image that has been posted as a file to the chatter. I have been able to do this for a User Profile image by sending &oauth_token=(my oauth token) as a query parameter, but cannot get it to work for the image thumbnails.

The Url i am trying to use is the renditionUrl240By180 property on the attachment item.

I have a url that looks like this:

https://na15.salesforce.com/services/data/v30.0/chatter/files/069i0000001S2RvAAK/rendition?type=THUMB240BY180&oauth_token=(my oauth token).

When i send this i get the following response: INVALID_SESSION_ID Session expired or invalid

You access_token that you got via the OAuth process must have either the web or full scope in the connected app.
