Integrated & Settings for Lightbox, Thickbox, Enhanced Thumbnail generation, Altering the image gallery layout + extras

OK, so it's not a patch, it's the whole module - there were too many things to roll a patch..

I have incorporated a number of things into this module (listed below), along with extra settings to control them. You can now switch between lightbox, thickbox and node images default display for the thumbnails on the admin/settings/node_images page. Lightbox2 and thickbox only become options when they are installed. The display switches back to default if the modules are disabled but the setting isn't changed.

All you need to do to get the functionality of these extra modules is download them, enable them and follow the instructions in the readme.txt for each module (especially lightbox2 which needs extra downloads). You do not need to put any extra js into the node_images folder, keep it all in the respective module folders.

Extensibility:

I implemented the theme_node_images_thumb function from ray007 (http://drupal.org/node/139349) but modified it to be as follows:
function theme_node_images_thumb_default(&$node, &$image, &$parameters) - default (built in) thumnail operation
function theme_node_images_thumb_lightbox2(&$node, &$image, &$parameters) - thumbnails with lightbox
function theme_node_images_thumb_thickbox(&$node, &$image, &$parameters) - thumbnails with thickbox

i also added a function _node_images_get_display_options() which returns a list of enabled display handlers. If you install lightbox2 or thickbox, then their options automatically become available. Adding new display handlers is as simple as adding the lines

to the _node_images_get_display_options() function and adding the associated function

to handle the appropriate superdisplayhandler thumbnail code - this is usually just one line.

I also rolled in a couple of other things because I needed them. They are listed below. One of the things I added was a control on the settings page to control where the node body is displayed on the node_images (image gallery) page. It defaults to the bottom, as per the module settings without this addition, but you can now put it at the top or get rid of it altogether.

Altogether, then, the module incorporates code and patches from the following issues:

* H3rnand3z & ray007 ('please help with thickbox modification' - http://drupal.org/node/139349)
* mad-admin & soflete ('Integrate with lightbox' - http://drupal.org/node/116515)
* Vallenwood ('Highly Enhanced Thumbnail generation - supersedes "Keep fixed thumnail size" - http://drupal.org/node/147538)
* terrybritton ('Altering the image gallery layout.' - http://drupal.org/node/135572 - *you will need his css file*)
* subspaceeddy ('div not closed in theme_node_images_gallery($element)' - http://drupal.org/node/145220)
* also further modifications by subspaceeddy to switch between lightbox, thickbox and default, and an ability to alter position of node body on 'Imaqe Gallery' page.

If you are using this version of the module, remember to get terrybritton's updated css file from http://drupal.org/node/135572. It does work without it though.

To install this module, rename your existing node_images.module to node_images.old (so you can switch back if you need to ;) and download this module into your node_images folder. Rename the module to get rid of the .txt extension. No essential database tables are modified so it is easy to switch back.

Let me know if this is of any use for anyone.

Also: I think that the thumbnail output stuff could probably be done more 'drupally' with a 'module_implements' call so that this module would not need to be modified to incorporate new display functions, but for now, this will do...
