Problems embedding photos
Well, at last I've succeeded in embedding all the photos in a long post on fitting a towbar to a Giulietta.
To do this it's absolutely essential to go to advanced editing from the outset and to go to the foot of the page (where I'd not looked...why would you!) and click on Attach Files to open a management window. From there you can browse for the files, upload them (maximum 6), then, returning to the edit window, drop them in various places amongst the text by clicking on the attachments icon and selecting the uploaded file.
Previously I had started with the attachments icon, which seems the logical thing to do, which then opened the management window where I uploaded photos, then returned to the attachments icon where I selected each photo in turn to place in the relevant place in the text.
In both case the edited reply window looked the same, but only the first sequence of actions resulted in success. The second sequence just resulted in dead attachments and subsequent uploaded files disappearing. A code appeared in the text, relating to the photos, which, when clicked, brought up the photo in a separate window. A day later those went dead.
This is really weird and it took me hours over several days to resolve the problem.
