Hi Matthew,
Do the images show correctly on the first refresh after you post a status to your Connections?
It is likely that your Connections administator has enabled security on the images, such that they only load if you are logged in to your Connections. The browser window which loads the images in WildFire does not itself login to Connections and therefore cannot access the images.
Normally this shows up as a default image of a grey background around the outline of a person.
To test it is the login issue, right click on one of the images and select properties. The URL should be something like
https://server.com/profiles/photo.do?key=5b7aa552-dab2-4b2b-cc09-8c6c6fe5d642
Open another browser window, make sure you are logged out of your Connections, and then open this URL.
Once this has loaded, log in to Connections, and then reload the image. If it reloads properly then it is the security settings on images.
If it doesn't load, or the URL is not in the above format, let me know.
Cheers,
Andrew
