ok I spoke too quickly, the template files that were saved out do not have the correct image file name references in them? they seemed to be pointing to the wrong place, at least as far as the live site went.
So, I was able to preview in the CP, but not on the live site, so I had to amend the script to make it visible live, but not in the CP.
I’ve managed to amend them in one section, but there is an image rotator script which accepts a matrix-style array, that is simply not picking up the correct values for the images. see stonebrideprivate.com to see the problem in the wild
the template contains this code
<div class=“span-3 last”>
<div class=“image-rotator”>
{page_image_matrix}
<div>
{site_url}{image_file}
<!—<div class=“image-title”>{image_title}</div> —>
</div>
{/page_image_matrix}
</div>
</div>
and the page_image_matrix value contains this code
a:5:{i:0;a🔢{i:1;s:16:"large_home_4.jpg";i:2;s:11:"Westminster";}i:1;a🔢{i:1;s:17:"skyscrapers_1.jpg";i:2;s:11:"Skyscrapers";}i:2;a🔢{i:1;s:13:"Harrods_1.jpg";i:2;s:11:"Square mile";}i:3;a🔢{i:1;s:16:"large_home_5.jpg";i:2;s:14:"City of London";}i:4;a🔢{i:1;s:16:"large_home_1.jpg";i:2;s:12:"Canary Wharf";}}
