Further to this, what is confusing to me is that when I click to browse server, all previous uploads, and any new uploads display correctly, but that's only in the upload/browse window. It's only when they are placed in the html editor and seen from anywhere other than top level that they don't display OK.
Do I need to create a third version of the following to get it to work in the admin area:
$kfm_userfiles_address = '../../_dataimages/_editor';
$kfm_userfiles_output = '_dataimages/_editor/';
$kfm_userfiles_admin-output = '_dataimages/_editor/';
If so, where on earth do I make changes to ensure that the images show in the admin section?
