EasySocial update 1.15 has broken my newsstream

Hi
I updated to Easysocial 1.15 using Easysocial's built in updater. It appeared to proceed without a problem.
Ever since the update, though, the news stream no longer shows photographs. If a user updates pictures, updates their profile pic or anything like that, it may (or may not) show in the news stream for a few minutes, and then disappears soon after that, to be left with a blank space or a 'broken image' placeholder. (see attachment)
If you click on the blank space or the placeholder, and click through to the original image, it shows no problem, but in the newsstream it remains an empty space.
Since I am using remote storage on Amazon S3 I am guessing that this is related - once the image is moved to S3 the newsstream can no longer show it? But it worked perfectly before the update!

Please can you help - this has completely ruined my site and makes Easysocial unusable for me,

Thanks
Rod
