The Attachments extension lets users attach subpages, files and external links to pages in enabled namespaces.

Attachments can easily be added through the user interface.
Attachments of an article are displayed in an automatically generated list at its end.
This extension integrates with the Vector and Minerva skins.

So how does it work?

subpages automatically count as attached to their parent page
When you upload a file through the Attach page action, a parser function {{#attach: Title}} is added to the descripiton.
When you add a link, the extension creates a subpage containing the {{#exturl: URL}} parser function.
Both parser functions set page properties, which are queried for the autogenerated sections.

Advanced features

#attach can also be used to attach a regular page to another regular page.
You can exclude subpages starting with a specific prefix from the autoindex with {{#attachments ignore subpages: prefix}} on the parent page.
You can access attachments before they are sorted with the BeforeSortAttachments(&$links) hook, where links is an associative array mapping string keys to HTML links. Return false to take over the sorting.

The Attachments extension provides the {{FILEPREFIX}} parser function to faciliate linking/embedding attached files.

If you attach an image Example.jpg to Somepage then you can embed the image:

from Somepage with [[File:{{FILEPREFIX}}Example.jpg]]
from Somepage/Subpage with [[File:{{FILEPREFIX:..}}Example.jpg]]
from Somepage/Subpage/Subsubpage with [[File:{{FILEPREFIX:../..}}Example.jpg]]

Note that the same also works with [[Media:...]] links.

Download and place the file(s) in a directory called Attachments in your extensions/ folder.
Add the following code at the bottom of your LocalSettings.php file:
```
wfLoadExtension( 'Attachments' );
```
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

You will need to enable the extension for the namespaces where you want to use it, e.g:

$wgAttachmentsNamespaces[NS_MAIN] = true;

Note that you should also enable subpages for these namespaces.

`$wgAttachmentsChunkListByLetter`	Boolean	whether or not the attachment list should be chunked by the first letter of list items. Defaults to `true`.
`$wgAttachmentsShowSubpageForm`	Boolean	whether or not the subpage form should be shown. Defaults to `true`.
`$wgAttachmentsShowLinkForm`	Boolean	whether or not the external link form should be shown. Defaults to `true`.

Enable $wgCountCategorizedImagesAsUsed to exclude attached files from Special:UnusedImages.
Attachments and external URLs are both stored as page props, meaning they can be queried with API:Pageprops and API:Pageswithprop.
Set $wgForeignUploadTargets to [], if you want to prevent users from circumventing this extension through the upload dialog.
If new attachments do not show up, it might be because you have many jobs in your job queue.

This extension is essentially a complete rewrite of PerPageResources by Mathias Ertl, which consists of Extension:Resources, Extension:AddResource and Extension:ExternalRedirects. This extension replaces all three, notable differences are:
