Hi Folks
Subject line says it all, really.

Site was created in NOF11, exported as a template, brought back into
NOF12, all seemingly OK. (apart from the uninvited optimisation of
images, but we knew about that).

Some major changes to several pages of the site in NOF12 this evening -
did an 'upload entire site' with 'changed pages only' ticked - and NOF
12 has trashed a whole load of images - they've just disappeared....

I've had to go back to the old NOF11 site (three revisions old!) in
order to keep something sensible online. And there's me just spent some
money on magazine advertising to drive traffic to the website!

Where does one start to untangle a problem like this, please ??
