Topic on Extension talk:PageImages

I enabled the popups for pages in the Project namespace with $wgContentNamespaces = [ NS_MAIN, NS_PROJECT, NS_CATEGORY, NS_USER ]; in my LocalSettings.php. The popups are working indeed, but without any images. The parameter "Page image" is also missing in the page information table of articles in the Project namespace (even if an image is inserted which triggers the popup on normal articles).

It isn't quite urgent, but I'd like popups with images to be shown also for those articles. Does anyone know a solution? Thanks in advance!

Extension:PageImages#Configuration says to use $wgPageImagesNamespaces. I haven't tried it.

You'd have to set $wgPageImagesNamespaces accordingly, since it defaults to NS_MAIN.

After the 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)
