Addition of a thumbnails list into Lightbox2

Second try for the attachments:

I have downloaded a fresh copy of Lightbox2 module and applied the patches and it works for me.

I'm going to replicate the steps that I followed here, I hope this helps:

1. Download and enable the following modules: Lightbox2, CCK, FileField, ImageField, Image API, Imagecache.
2. Create 2 preset for Imagecache (full and thumbnail sizes):
   1. Go to /admin/build/imagecache/add
   2. Enter "lightbox-thumb" and click "Save Preset".
   3. Chose "Scale and Crop".
   4. Enter 80 in both field and press "Update Action".
   5. Go to /admin/build/imagecache/add
   6. Enter "lightbox-full" and click "Save Preset".
   7. Chose "Scale and Crop".
   8. Enter 500 for width and 450 for height, then press "Update Action".
3. Create a new content type to put everything together:
   1. Go to /admin/content/types/add
   2. In "Name" field enter "Lightbox2 (extended)"
   3. In "Type" field enter "lightbox2_extended".
   4. In description field enter "Add a thumbnail list navigation to lightbox2 module".
   5. Click "Save content type".
4. Add the image field to the new content type:
   1. Go to /admin/content/node-type/lightbox2-extended/fields
   2. Under "New Field": enter 'Image' as Label field, enter 'image' as Field name (a-z, 0-9, _) name, select 'File' for Type of data to store., select 'Image' for Form element to edit the data.
   3. Click 'Save'
   4. Under Global settings choose "Unlimited" for Number of Values:. In case you get lost this is in page /admin/content/node-type/lightbox2-extended/fields/field_image
   5. Click 'Save field settings'
5. Go to /admin/content/node-type/lightbox2-extended/display and choose 'Lightbox2: lightbox-thumb->lightbox-full' for Full node and click 'Exclude' for Teaser.
6. Click 'Save'.

By this point you should be able to create a new node type "Lightbox2 (extended)", add some images, and see how the Lightbox2 module displays the upload images.

Now the Extended part:

1. In your terminal go to the Lightbox2 module root directory, ie: /sites/all/modules/lightbox2
2. With your favorite text editor create a file named 'lightbox2_dir.patch' and add patch lightbox2_dir.patch, then save the file.
3. Still in the module root directory run:
   patch < lightbox2_dir.patch
4. Go to the 'css' directory (cd css)
5. With your favorite text editor create a file named 'lightbox2_dir_css.patch' and add patch lightbox2_dir_css.patch, then save the file.
6. Still in the css directory run:
   patch < lightbox2_dir_css.patch
7. Go to the 'js' directory (cd ../js)
8. With your favorite text editor create a file named 'lightbox2_dir_js.patch' and add patch lightbox2_dir_js.patch, then save the file.
9. Still in the 'js' directory run:
   patch < lightbox2_dir_js.patch
10. If everything went fine you should now flush your cache before we enable the thumbnail option.
11. Go to '/admin/settings/lightbox2', you will now see a new checkbox under Lightbox2 lite fieldset.
12. Check Use thumbnail list and save the form.
13. Go to the node "Lightbox2 (extended)" that you previously created, refresh, open the lightbox and... "I really hope you can see the thumbnails".

Well, I guess this is all. As I said before I haven't go farther because I want to check with the developers if the changes that I've done so far are ok.

Cheers.
