[edit] Enabling PNG uploads in MediaWiki

By default, MediaWiki does not allow PNG uploads. Two changes need to be made:

1. Allow the PNG extension (MediaWiki)
2. Set MIME type for PNG (Apache)

[edit] Allow the PNG extension

Verify that $WIKI/includes/DefaultSettings.php has an entry for PNG in the list of extensions:

 $wgFileExtensions = array( 'png', 'gif', 'jpg', 'jpeg' );

If not, set the $wgFileExtensions variable in your LocalSettings.php file.

[edit] Set up MIME types

In Apache configuration file /etc/httpd/conf/magic, make the following change (universal diff format, add lines with '+' in front):

[root@dell conf]# rcsdiff -u -r1.1 magic
