Have just tried again and am now able to upload most images.   However, I am still having intermittent issues.

Earlier today I had some other unusual issues elsewhere on the site which I took screen shots of:

- Page not found message when I was checking out an includlet in the same Category

- Permission denied message when I was trying to log back in to the website and add the verification.

I seemed to have to log in repeatedly.

Not sure whether this is a problem my end or a bug - not aware of any other issues my end.
