Yammer API issue with thumbnail image
<p>We are posting a message on yammer with og_image parameter set to a valid url that serves the image. But in the yammer user interface, message appears with a broken image. URL for an example image is "<a href="http://edubrite-com.edubrite.com/oltpublish/att/ae6e7132-8a2c-11e4-a3d9-00163e0054ca?t=l" rel="nofollow">http://edubrite-com.edubrite.com/oltpublish/att/ae6e7132-8a2c-11e4-a3d9-00163e0054ca?t=l</a>" </p>

<p>As you can see the url is valid but doesn't have a file like name at the end. Does the og_image needs to be ending with a file name?</p>

<p>We are using the API - <a href="https://developer.yammer.com/docs/messages-json-post" rel="nofollow">https://developer.yammer.com/docs/messages-json-post</a></p>

<p>Thanks for any suggestion. </p>
