Your Moodle version

Activities: Lightbox Gallery

This resource allows you to create 'Lightbox' enabled image galleries within your Moodle course. As a course teacher, you are able to create, edit and delete galleries. Smallthumbnails will then be generated, which are used for the thumbnail view of the gallery.

Clicking on any of the thumbnails brings that image into focus, and allows you to scroll through the
gallery at your leisure. Using the Lightbox scripts creates nice transition effects when loading and
scrolling through the images.

    Hi all,

    I've just put up an update for the 2.7 and 2.8/2.9 versions of the plugin, the change notes for each are the same:

    * mod_form: Show all settings without needing to click 'show more'
    * GITHUB-69: Fix overlay to be on top of the clean navbar
    * GITHUB-66: Add a download link to the lightbox interface
    * Bug: Prevent error displaying when adjusting a thumbnail without first picking up/down

    Hi all,

    I've just finished a round of testing for lightboxgallery against Moodle 3.0 RC2. I couldn't find any regressions in functionality or issues in the install/upgrade process when using the most recent release - as such I've flagged it (v2.8.0.5 of the plugin) as compatible with Moodle 3.0

    I am writing to report a bug that when adding an image having the same name with an image that is already added in the gallery activity, the gallery cannot upload the image and gives an error message. It is not user-friendly, especially for students to get a error message with no tips about what they can do. I hope this bug can be solve soon.

    I have just updated Lightbox Gallery update Release on moodle 2.9.

    Since this update, teachers are not able to use Lightbox gallery. When we use an existing gallery or add new Lighbox Gallery activity, it gives "Internal Server Error".

    Your help is highly appreciated.

    Hi Imran,

    Would you be able to provide more detail "Internal server error" could be any number of things. If possible, it'd be good to know what you're seeing in your web servers error log when the error shows up.

    Hello Imran and Adam,

    I'm not sure if it's related, but sometimes I also get this error when trying to access a Gallery after updating through Moodle. I've found that it's due to the permissions on the plugin directory/files. Once the permission are reset to what it was previously, the gallery/plugin works fine.

    Hi Adam, Ali,

    Thanks for your reply.

    It is showing 500 Internal Server Error.
    Will it be possible, if I update it back with older version or problem may become more complexed.

    Following is message that appears as I click any Lightbox gallery:

    "The server encountered an internal error or misconfiguration and was unable to complete your request.

    Please contact the server administrator, and inform them of the time the error occurred, and anything you might have done that may have caused the error.

    More information about this error may be available in the server error log.

    Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."

    Part of your error message states: "More information about this error may be available in the server error log."
    That's where you'll need to check what the actual error is.

    Simply replacing the plugin with the older version will have Moodle complain about the version mismatch if you've already run Moodle upgrade with that new version in place.

    Hi Bert,

    Please report your issue at:

    It'll help if you can provide more detail when you make your report. What page are you trying to access? What version of PHP are you using? What version of the plugin are you using? Do you have access to the error_log of your webserver to supply the actual error message?

    i have a question, is it possible to turn of the the download button?

    Hi Mirko,

    Currently there is no way to turn off the button. Were you wanting to turn it off because its showing up weird, or to prevent people downloading images?

    I ask because if its the latter, there won't really be anything stopping a user just right clicking on the image and saving it anyway.

    First of all, I'm new on moodle.
    I'm having a problem trying to find the folder where the image are stored in. Do you know how it works?

    Hi Adam. Many thanks for providing this plugin to the community; its functionality is really appreciated by our staff and students, and we’re really grateful to you for your efforts to maintain and update it.

    On that note, please could I quickly query whether you have any plans to update the plugin to be fully compatible with Moodle v3.1, and its new Global Search feature in particular? To clarify: while we’ve tested the Lightbox Gallery plugin under v3.1 and all of the core functionality seems to work fine, we’ve found that instances of the activity are not searchable via v3.1’s Global Search feature. Please see the following screenshot for details, which lists all of the available areas that can searched under v3.1 (note that these settings are available via: Site Administration -> Plugins -> Search -> Manage Global Search):

    Note also that the above screenshot was taken on a v3.1 system where the Lightbox Gallery plugin is installed and available. However, as you can see, the Lightbox Gallery activity is not listed as being available to be searched. Obviously, this is likely to be a significant problem/cause of confusion for users who might want to search for specific instances of the Lightbox Gallery activity across Moodle.

    I’m not a developer, but my understanding is that mod plugins can be made searchable relatively easily via the addition of a new search class within the plugin’s codebase (located at ../classes/search/activity.php). Please see the following for further details:

    We really hope this search capability can be added to Lightbox Gallery as I’m sure it would be a huge benefit to our users (as well as those of other v3.1 systems) and, again, many thanks for all your efforts to develop this plugin and share it with the community.

    Best wishes,
