MG 2.2 Media Gallery 2.2 - Lightbox navigation, attachment mirroring and more!

lightbox_5.pngXenForo Media Gallery (XFMG) 2.2 sees a range of new features and improvements. Some of these are a result of new integrations with XenForo 2.2 itself, while others are exclusive new features to XFMG itself.

Lightbox navigation​

Starting with XenForo 2.2 we are introducing a brand new lightbox which as well as being a much improved user experience also affords us some flexibility in how and where we use the lightbox.

One such use case which we couldn't resist treating you to for XFMG 2.2 is of course navigating through media items in the media gallery. Before we get into it, this is what the experience looks like.

The lightbox as used in the media gallery supports all media types including media embeds, video and audio.

By default the lightbox opens up a very useful sidebar which displays most of the information and functionality that you get if you go to the full media page. If you prefer not to view that information then you can collapse the sidebar. Sections within the sidebar can be expanded and collapsed as required and we remember your preferences here so only the relevant sections are displayed.

The lightbox will initially only contain the items from the current page but, as you can see in the video, you can continue navigating beyond the page you're on and we will load additional items from the subsequent page dynamically.

If you need to view the full media details and access the full functionality you just need to click the "New window" icon in the lightbox toolbar or click the caption of the image.

You can navigate through any media list in this way be that the list of media in an album or category, all media in the New media page or the entire media gallery via the media index.

We think this is an awesome way to navigate through the media gallery but if you prefer to keep things as they are (we won't be offended!) then you can disable it:


We should also take this opportunity to note that all of the lightbox functionality you see here is a general concept baked into the core lightbox itself so should any add-on developers which to add a similar navigation or sidebar concept to their existing lightbox implementations then this should be fairly trivial to do.

Attachment mirroring​

For a very long time you have been telling us that you would like to have a slightly closer relationship between attachments in threads and posts and the media gallery, and the new "Attachment mirroring" system in XFMG 2.2 aims to somewhat bridge that gap. It starts with a forum-level or media category-level configuration:


While viewing a media category you can pick which forums attachments are mirrored from...


... and while viewing a forum you can pick which media category attachments are mirrored to.

Once you have specified which media category your forum should mirror attachments to, any attachments which are added to posts in that forum will be automatically created as media items in the specified gallery.

As an example, here is a post containing an image I have attached inside the "Travel and nature" forum:


And here it is now displayed in the media gallery:

localhost_22x_media_navagio-jpg.134_ (2).png

As you can see here we make display a clear reference to the fact that the media item originated from a particular thread with the "Originally posted in: Thread 'Travel photos'" line. Thins links and takes you straight back to the post where the attachment was originally posted.

While viewing the thread, we also make clear that the attachment has been also posted over in the media gallery too. Of course images open up in the lightbox and when you do so, the media information opens up in the sidebar with an additional link that links back to the full media gallery view if needed:

But what about all of those existing threads with great images you might want to bring over to the media gallery? We've added a rebuild which will take care of that for you:


This allows you to have old items that were not yet mirrored synced into the media gallery, plus it will move or remove items from the media gallery as applicable if you disable mirroring or change the target category.

But wait... there's more!​

In addition to these great features we have also added (or in the process of adding) support for the following previously announced XF 2.2 features including:
this looks great! Forgive me since I don't use the media gallery. Does this mean that attachments are re-usable when mirrored to media gallery? Seems media gallery images can be used again in gallery tags?

Nice one, the Media Gallery lightbox is a much needed addition, will be great to get more engagement with media gallery items :)
Having the same lightbox viewing option for forum posts and for media gallery posts will be most appreciated.
Thank you, thank you, thank you! For years the gallery was all but pointless for myself, this is a huge improvement. 🥰
Attachment mirroring is awesome and a really long-awaited feature!

Now if we could also get an option for users to upload straight from a post to a specific category or album it would be perfect, but let's see what Add-on authors (or XFMG 2.3?) can come up with.

Keep up the good work (y)

Will the attachment mirroring also work for videos?
If so:
  1. Will it be possible to set different destination categories for images and videos?
  2. Would those videos be transcoded?
It will work for videos (and audio) provided they don't need to be transcoded -- anything that requires transcoding won't be mirrored. There isn't an option to choose the category by content type.

Can you clarify what "requires" transcoding?

There we go, two new suggestions ;)
What happens if the gallery image is used in multiple threads? Will there be more than one link?
The media item being embedded in a thread isn't really related to the mirroring case, which is for bringing post attachments into the media gallery.

But there will only be one link -- the content that relates to the attachment that caused the media item to be created. (There are theoretical cases where this could change over time, though they aren't common at this time.)
These are great features!
Could you please show us what the activity summary of XFMG look like and what the settings are?
With images there is a much higher risk to send out something inappropriate. What controls do we have over what is sent out?
