Manual:Installing third-party tools

Image thumbnailing
requires either ImageMagick or GD library. ImageMagick is recommended since it produces better quality thumbnails. It can be downloaded from https://imagemagick.org/. GD can be downloaded from https://libgd.github.io/.

ImageMagick
MediaWiki can be configured to use ImageMagick to do dynamic resizing and thumbnailing of images. ImageMagick is available for Windows, Unix, Mac OS, and Linux from http://www.imagemagick.org/script/index.php. Once ImageMagick is installed, you must enable ImageMagick and point MediaWiki to the  or   program on your computer in LocalSettings.php like this:

For information on configuring MediaWiki for images in general, see and Manual:Configuration settings#Images. For information on installing ImageMagick on Windows, see ; as PHP on Windows comes with GD, it's easier to use GD than ImageMagick.

Mathematical formulae

 *  See  

The Math extension provides support for rendering mathematical formulas on-wiki via Mathoid and other backends. This extension comes with MediaWiki 1.38 and newer.

System-generated emails
MediaWiki by default uses php to send email notifications to users if they are  and in the user's preferences. Common local mail transfer agent software for sending messages on Linux systems are Postfix, Sendmail, or Exim. Once a local mail transfer agent is installed, you must set the  variable in the file   to point to the correct executable file of your mail server software. See the PHP documentation.

Alternatively you can use to connect MediaWiki to an email provider, no local mail transfer agent needed.
