You wouldn't believe it, but all I get is a grey box where your photo should be.
Don't worry about it - these work computers are antique boat anchors like our IT people - we can't modify PC's due to admin rights.
Thanks for your time and assistance.
Also, should perhaps mention it now, there seems to be a timing issue. For example, when writing up a response on the Forum, if it's not done quickly enough and uploaded, it won't be accepted and it automatically logs me off the forum.
This happens both at work and at home. (The home computer is NASA quality, though currently 'runs' Vista ... if indeed Vista runs!)
