Not certain what all you did with your software but the OOF backdrop in the first image has a more pleasing tone to it as a blur than the second one. The second one has almost a pattern look to it which doesn't really fit in with the subject in front.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
