Imagecache has written its subfolders and seems to be working, as is Lightbox2.
I've created a gallery view for image nodes but get the following error:
>>
user warning: Unknown column 'node_data_field_image.field_image_value' in 'field list' query: SELECT node.nid, node_data_field_image.field_image_value AS node_data_field_image_field_image_value, node_data_field_image.field_image_fid AS node_data_field_image_field_image_fid, node_data_field_image.field_image_title AS node_data_field_image_field_image_title, node_data_field_image.field_image_alt AS node_data_field_image_field_image_alt, node.title AS node_title, node.changed AS node_changed, node.nid AS node_nid FROM node node LEFT JOIN content_type_image node_data_field_image ON node.vid = node_data_field_image.vid WHERE (node.status = '1') AND (node.type IN ('image')) LIMIT 0, 10 in /home/lroca/public_html/drupal/includes/database.mysql.inc on line 172.

Do you have any clues what I have missed? - what does field_image_value relate to ? and why would it be missing?
thanks
Neil
