Probably not in the right section but anyway:

Firstly, as regards the cropped images issue, it seems to be browser-related: MS Edge performs as said, Chrome works ok (once Flash allowed) and Firefox doesn't open at all - not tried anything else. Presumably a new method will be needed with the death of Flash anyway.

Secondly, I was not allowed to reply to the original thread as not having sufficient rights, which is why I posted a new one. Similarly, I tried to post to the Technical thread the other day and it told me my post was awaiting moderation.
