Afterthe change, you'll have to run refreshLinks.php to generate the Page image information for those namespaces (hopefully, you can use the --namespace parameter to process only pages on the affected namespaces, since that script is very resource-intensive)

When a page is saved with a local image, the parser runs the hooks ParserMakeImageParams and LinksUpdate.The PageImages extension responds to these (and other hooks) and inserts a new property for the page into the page_props table.The property name is page_image_free and its value is the name of the image.

All images in the page are collected and a score for each image is calculated.The image with the highest score is selected as the page image.If the wiki is configured such that images contain metadata that specifies images are not freely licensed, the image with the best score that is also freely licensed is also stored.If no suitable image is found or all the images score badly (i.e. have a negative score), the page will not have any images.

If $wgPageImagesLeadSectionOnly is true, only images in the lead section will be considered.Currently this is true for only Wikipedia projects; all other projects can pull images from outside the lead.

The best possible page image on Wikimedia wikis is one of the first four images in an article which has a width/height between 400-600px and a height/width which is twice the value of the other dimension.

The pageimage only changes when a link in an article changes. For emergencies, please add/remove links from the page, reverting if necessary.Purging will not work.For larger emergencies please file a Phabricator ticket.

This likely relates to video content in your article.If a video file begins with a blank screen, that will become the default thumbnail for the video and if used as the page image, it will become the page image.We are currently working on a fix for this, that will allow you to change the default thumbnail of a video.See: phab:T92457 and phab:T22647 for further information.

Modern pages and web parts are designed to be fully responsive across devices, meaning that images used in web parts will scale differently depending on where they are shown, which layout is used, and the device on which they are being viewed. For example, modern pages are designed to look great on mobile devices, and automatic image scaling helps create that attractive experience.

Because of the responsive page design, there is not a specific height or width in pixels that will ensure that an image will maintain a specific shape across devices and layouts. Images are resized and cropped automatically to show the best possible result across a variety of devices and layouts. However, there are some guidelines that can help you make sure your images look great on your pages.

An aspect ratio is the relationship between width and height of images. It is usually expressed as two numbers, such as 3:2, 4:3 or 16:9. The width is always the first number. As an example, a ratio of 16:9 could be 1600 pixels in width by 900 pixels in height. Or, it could be 1920 x 1080, 1280 x 720, or any other width/height combinations that can be calculated to equal 16:9. You can find aspect ratio calculators online and in some photo editing tools to help you determine the aspect ratios of your images.

A page can be laid out with sections that include different column types and layouts, such as full-width columns, one column, two columns, three columns, one-third left and one-third right columns. A general rule for images expected to fill the width of a column is that they be at least as wide as the column in which they are placed. For example, an image in an image web part in one column should be at least 1204 pixels wide. Following are the width guidelines for each of the column layouts:

The height of images placed within other column layouts will depend on your aspect ratio. Here are height/width guidelines for 16:9 and 4:3 aspect ratios (rounded up/down to the nearest pixel). This is helpful to keep your images at a width and height that scales appropriately for mobile devices, for example.

The layouts in the web parts you use will also affect how your images scale. The following examples show different web parts and their layouts within one column, and the aspect ratios that are used in each.

Images will expand to the width of the section containing the web part. You have the option to change the aspect ratio or free-hand crop using the Image toolbar, or use the resize handles to make your image bigger or smaller.

Images look best when they are landscape or 16:9 or greater in aspect ratio, and when they are at least 1 MB in size. Also, be sure to set a focal point to the keep the most important part of the picture in view, especially when the picture is used in thumbnails, news layouts, and search results.

Page thumbnails are shown in places like search results, highlighted content results, news posts, and more. By default, the thumbnail comes from the page title area or from the web part that is in the first order on the page (such as top left of a page layout). You can override the default and change the page thumbnail. When you do so, it is best to use an image with a 16:9 aspect ratio.

When you add an image to a page title area or hero web part, it is also best to set the focal point in the area of the image that you want to always display. To learn more about setting a focal point for these two scenarios, see Change the focal point of an image in the Hero web part and Customize the title area in a page.

Images are expected on a SharePoint page and can often show details that otherwise would take, well, a thousand words. You can add images from your local computer, SharePoint media libraries, or links from other locations on your site or the web.

Automatic alternative text When you insert an image, alternative text (for people with screen readers) is automatically generated. In many cases, the text is automatically saved with your image, unless you change or remove it. In cases where the confidence level of the alternative text for the image is not high, you'll see an alert on the image that allows you to review and change or keep the alternative text.

Specify a destination library where you want to store the file.

We recommend that you specify an Asset Library as the destination. To learn how to set up an Asset Library for image files, see Set up an Asset library to store image, audio, or video files.

In the Arrange group, click Position to change the position that the image takes in the space. In the drop down, you can pick a floating position as either left or right, or an inline position of top, middle, or bottom in relation to other objects.

In the Size group on the ribbon, you can resize the image. If you leave the Lock Aspect Ratio checked, then the Horizontal and Vertical sizes are linked. When you change one, the other will change to a proportionate size as well.

You can also add an image to any Web page that has a Page Content field control, by using the HTML Editor. When you use the HTML Editor to add an image to a Page Content field control, the image is also stored in a library, so that when the image in the library is updated, pages that use the image automatically use the new image.

Alternate Text Type text that briefly describes the image. This text is displayed instead of the image if the page viewer's browser does not display the image. Alternate text is also read by screen readers.

Hyperlink The image can optionally act as a hyperlink. Type the desired hyperlink target in this box. You can also use the Browse button to locate a target for the hyperlink. Select the Open This Link In New Window check box if you want the hyperlink to open in a new browser window.

Alignment You can change the position of the image within the field control by choosing from the Alignment list. Since a Page Image field control is sized to fit the image, this option does not have a noticeable effect when used on an image that is in a Page Image field control.

Specify Size Select this option if you want to specify the size of the image on the published page. This overrides the image file's size properties. If you select this option, you must set the width, the height, or both for the image by using the Width and Height properties.

Maintain aspect ratio You can use this option to preserve the ratio of the image's width and height. If you select this option, you can only set either the width or the height of the image, because the value that you choose for the image's width or height determines the value of the other dimension based on the ratio of the original image width and height.

If the image that you want to add to a page is not available in the Image library, you can add it if you have Contribute permissions. For more information on adding an image file to a library, see the article Add one or more files to a library.
