Make sure uploads are enabled in PHP
The following needs to be set in php.ini: If this is not set, PHP scripts cannot use the upload functions, and MediaWiki's uploads will not be enabled. If the open_basedir directive is set, it must include both the destination upload folder in your MediaWiki installation ("{$IP}/images") and the 'upload_tmp_dir' folder (default system folder if not set). The addition of the 'upload_tmp_dir' can avoid messages like "Could not find file "/var/tmp/php31aWnF" (where in this example the 'upload_tm...
Check for Windows and IIS users
Set %SystemRoot%\TEMP to have permissions for the Internet Guest Account (IUSR_MachineName, or IUSRfor IIS 7+): Read, write and execute;
Check directory security
The upload directory needs to be configured so that it is not possible for an end userto upload and execute other scripts, which could then exploit access to your web directory and damage your wiki or web site. Set the /images folder (or the /uploadsfolder in previous versions) to have permission "755": 1. Usercan read, write and execute; 2. Groupcan read and execute; 3. Worldcan read and execute. If using SELinux, make sure to adjust the ACLs accordingly (see there).
In MediaWiki version 1.5 and later, the attribute to be set resides in LocalSettings.php and $wgEnableUploadsis set as follows: To disable upload functionality, set the attribute to false:
InstantCommonsis a feature, enabled with a configuration change, which gives you immediate access to the millions of free (freely licensed) files in Wikimedia Commons.
Per default, all registered users can upload files. To restrict this, you have to change $wgGroupPermissions: 1. To prevent normal users from uploading files: $wgGroupPermissions['user']['upload'] = false; 2. To create a special group called "uploadaccess", and allow members of that group to upload files: $wgGroupPermissions['uploadaccess']['upload...
You can add $wgFileExtensions in LocalSettings.phpto allow uploads of other desired file types. For example, you can change the $wgFileExtensions line to look something like or or However, certain file extensions are prohibited ($wgProhibitedFileExtensions, formerly $wgFileBlacklist for MediaWiki 1.36 and earlier) and cannot be uploaded even if add...
By default anonymous uploads are not allowed. You must register and log in before the upload filelink appears in the toolbox.
For information about automatic rendering/thumbnailing of images, see Image thumbnailing. For problems with thumbnailing, see Image Thumbnails not working and/or appearing. If the file is not visual (like an Image or Video) a fileicon is used instead. These are generated by the iconThumb() function in the File class in the FileRepo group. Icons sto...
Browsers tell the server the size of the file to be uploaded before it actually sends the file. If the upload is too big, it is rejected by the target (server) and the upload fails providing multiple errors depending at which layer the limit was imposed: 1. If it's a server limit (nginx, Apache) on the maximum amount of transmitted data, it may sim...
By default, MediaWiki will scan all uploads that appear to be ZIP archives and reject any that contain Java .class files. This is a security measure to prevent users uploading a malicious Java applet.For non-public sites only, use the following to disable this check: This setting can be used as a work around for allowing MIME types to be accepted i...
If you want to allow a user to directly upload files from a URL, instead of from a file on their local computer, set $wgAllowCopyUploads = true. By default, upload by URL are only possible using the API (or extensions such as UploadWizard). To make the option usable from Special:Upload, you need to set $wgCopyUploadsFromSpecialUpload to trueas well...
Wikimedia Commons (WC) is a multilingual repository of freely licensed or freely usable media files, used primarily by many wiki projects, including WikiScripts (WL). The process for embedding a file from WC into an article is no different from that for embedding media uploaded directly here.
This page in a nutshell: Freely licensed files should be moved to the Wikimedia Commons so all Wikimedia Foundation projects can use them.
