1513cd66b6 Bug 29803: Prevent local cover image to be hidden if Coce is enabled
If Coce is enabled by no image are returned by the service, then no
other image will be displayed (actually un-hidden)

The getURL is returning early if no image is returned by the service and
the "done" flag is never set.

Test plan:
Add a local cover image to a bibliographic record (ktd biblionumber=14
is good)
Set CoceHost = http://coce.bywatersolutions.com
Select all CoceProviders
Enable OpacCoce

=> If no image is returned by Coce then the local image should be
displayed anyway

819095aa21 Bug 28180: Correctly guess if images have been loaded
window.load won't assure us that the images loaded using JS code are
correctly loaded.

This patch adds a flag to the different providers when the images are
fully loaded.

Note that the img.naturalHeight check is not working for google jackets
and is actually not needed (test with a bib record with and without
google jacket and confirm that it's working as expected).

fad97080e9 Bug 28180: Add a lightbox gallery to display cover images - detail page, OPAC interface
This patch is the OPAC version of
  Bug 28179: Add a lightbox gallery to display cover images - detail page, staff interface

But there were several difficulties as the staff and OPAC code diverged
a lot.
First we are going to apply the different enhancements that have been
made staff-side:
- Display all the local cover image on the bibliographic detail pages
(before this patch only the first one was displayed)
- The slider functionality added by bug 25031

Test plan:
All the cover images are affected, all the different sources will be
tested.
All the steps will be done on the same bibliographic record.
1. Local cover images
 a. Turn on OPACLocalCoverImages and AllowMultipleCover
 b. Add several local cover images to a bibliographic record
 c. Add several local cover images to an item
 d. Click on an image and confirm that it is displayed in a gallery and
 you can navigate see all the images attached to the bibliographic
 record
 e. Same for items
2. Adlibris
 a. Turn on AdlibrisCoversEnabled
 b. Edit the biliographic record and add an ISBN that will return a
 cover image for this service (9780670026623 for instance)
 c. Display the cover images in the gallery
 d. Note the link to the adlibris.com website at the bottom
3. Amazon
 a. Turn on OPACAmazonCoverImages
 b. Display the cover images in the gallery
4. Coce
 a. Turn on OpacCoce, set CoceHost to "http://coce.tamil.fr:8080"
 and select some values for CoceProviders.
 b. Display the cover images in the gallery
5. Custom cover images
 a. Turn on OPACCustomCoverImages and set CustomCoverImagesURL to https://covers.openlibrary.org/b/isbn/{isbn}-M.jpg
 of anything else meaningful
 b. Display the cover images in the gallery

QA Note: Other sources have been removed by this patch but will be
re-added by follow-ups

9570439c50 Bug 9580 Cover images from Coce, a remote image URL cache
Add to Koha support for displaying Book cover requested to Coce, a
remote image URL cache:

  https://github.com/fredericd/coce

With this enhancement, cover images are not fetched directly from
Amazon, Google, and so on. Their URL are requested via a web service to
Coce which manages a cache of URLs.

Three cover image providers are now available: Google Books (gb), Amazon
(aws), and Open Library (ol). Two system preferences enable this service:

  - CoceHost - URL of Coce server
  - CoceProviders - Ordered list of requested providers. For example
    gb,aws,ol, will return the first available URL from those providers.

Several advantages to this architecture:

  - If a book cover is not available from a provider, but is available
    from another one, Koha will be able to display a book cover, which
    isn't the case now
  - Since URLs are cached, it isn't necessary for each book cover to
    request, again and again, the provider, and several of them if
    necessary.
  - Amazon book covers are retrieved with Amazon Product Advertising
    API, which means that more covers are retrieved (ISBN13).

Test plan:

- Apply this patch, and test with 'Bootstrap' themes
- You can verify that nothing has changed on OPAC result and detail
  page, since new syspref haven't been filled
- Install Code: https://github.com/fredericd/coce
  Or ask me directly for the URL of a Coce server
- In sysprefs, tab Enhanced content, modify:
  CoceHost -- enter the URL of your Coce server
  CoceProviders -- fill with: gb,aws,ol
- Do a search. On result page, and detail page, you will see cover
  images originating from the 3 providers: fly over the image to see its
  URL. Try to compare with a Koha with just GoogleJacket or Amazon cover
  to confirm that you have more images. Verify that it's quick, and even
  quicker for cached images URLs.
- Check that Browse Shelf functionnality works properly.
- The ID sent to Coce is EAN or ISBN. Try with various type of biblios. DVD
  have often EAN, but no ISBN.
- You can try with those sysprefs:
    CoceProviders: aws,gb
    CoceHost: http://coce.tamil.fr:8080
  and this EAN (or ISBN): 3333297517744
  => OPACAmazonCoverImages enabled doesn't display a cover because, it's a DVD
  => Coce find and display the DVD cover.
