This extension can be enabled or disabled using WikiFeatures. (Special:WikiFeatures)

Welcome to the new image gallery! New image galleries are in Labs for a preview period, to allow communities to try out this updated gallery design. Read the announcement here. For now, this new style is available for creation and modification using source only, and is not supported within the classic rich-text editor or the VisualEditor. Gallery creation and editing tools are currently in development and will be available soon.

The new image galleries provide different layouts for up to the first eight images, with some images varying in size depending on the total number of images.

You can see various layouts here.

New image gallery basics

Here are some things you need to know about the new image galleries:

  • All slideshows will be converted to new image galleries. Sliders will be unaffected.
  • Not all galleries will convert to the new style when this feature is enabled. See the section below for more information on what will be converted. If you disable the new image galleries in Labs, all of your galleries will convert back to the old style.
  • The gallery shows a maximum of eight images by default on the page. If there are more than eight images, a "Show More" button will appear. Clicking on this button expands the module and displays twelve additional images. "Show Fewer" collapses the module back to the first eight images.
  • The gallery can be adjusted to show all images by default (up to 100) if you add the parameter  expand="true" to the gallery tag (<gallery expand="true">). Clicking on the "show more" button at the bottom will show up to 100 more images instead of the next twelve.
  • The gallery respects image order.
  • Gallery parameters that customize border color and caption size do not function with the new gallery design.
  • There is a limit of 3,000 images for new image galleries. Any images that go beyond that will fail silently and not show in the gallery.
  • Once you enable the new image galleries in Labs, you will only be able to create and edit galleries via source mode (i.e. you will not see an "add image to gallery" button any galleries, nor will you see any tools in the classic rich text editor or VisualEditor.) New gallery tools are coming soon for the VisualEditor.

Previewing your wiki with the new image galleries

Before you turn this new feature on, you may want to see a preview of what your wiki's pages will look like with the new gallery style. We have created a way to preview individual pages with the new image gallery implementation by adding ?gallery=new to a URL. For example: http://arresteddevelopment.wikia.com/wiki/Rita_Leeds?gallery=new

FAQ

Why are only some of my galleries converting to the new style?

Check the source of the image galleries that are not converting. Do they have "link=" parameters in them? We have made a choice to not convert galleries that contain links, as some image galleries are used as navigational tools for wikis. If you want them to convert to the new style, remove all the links in the gallery and save.

Can I adjust the image cropping in the new style?

All images displayed in the new galleries are cropped square to allow for optimal use of space. The full image can be viewed by clicking on the image.

Why are the videos that I added to a gallery not showing up in the new image gallery conversion?

We are no longer supporting multimedia galleries. If you would like to display these videos, please create a separate gallery containing only videos, or embed them individually within your article context.

What happened to the slideshow feature?

We felt that we could address both the use cases for slideshows and image galleries with one feature. We welcome your feedback.

I want more than 8 images to show by default. Can I do that?

Yes. The gallery can be adjusted to show all images by default (up to 100) if you add the parameter expand="true" to the gallery tag (<gallery expand="true">). The "show more" button will need to be clicked to view additional images past the first 100.
