Loss of picture - now grey image

In waiting for a response regarding my query about having ‘clone’ on debit notes I have now noticed that my picture has gone and a grey image is there. This is not only on my picture but several others as well and I have included snapshot.

The Forum service provider has incurred an event which has caused the lost of some Avatars.
They have been informed - meanwhile some of us look as though we are now part of the “cloud”.
