Template:Information

 |[Source]

Usage
Copy and paste the following code into the image description when uploading new images, and don't alter it (example):

Summary

 * The "attention" field will generally not be used on a new upload, except for Notorphan or No source.
 * The "description" field should be used for an accurate description of the file's contents, preferably with link(s) to its subject(s). This information should be listed whether or not the template is used.
 * The "source" field should list the specific source that the item comes from, with a link to it. If the source is a website, the URL is mandatory. This information should be listed whether or not the template is used.
 * "Author" is an optional field for author/artist information.
 * "Filespecs" should be used to list specific information about any editing or processing the file has undergone -- this is critical for any image which has been modified from the original source. This information should be listed whether or not the template is used.
 * "Licensing" is an absolutely non-optional field which must be used to indicate the license, and "GFDL" or "public domain" licenses must not be used for anything copyrighted by Valve or an affiliate. Again, the copyright templates to be chosen can be found at Category:Copyright templates. Most of the time, the template used for the pictures seen on this wiki is Gamescreenshot, which is Fairuse by default. This information must be listed whether or not the template is used.
 * "Other versions" should be used to indicate when alternate but non-duplicate versions or formats of a file are available.
 * The "cat" fields are for image categories. For now "cat type", for example "Category:Half-Life 2: Episode One screenshots", is the primary one to be used. You'll find the needed category/categories here. Be careful, however. If all the images from the games fall into the Gamescreenshot license, only in-game images and models viewed in a model viewer fall into the "screenshot" category, while other images, such as extracted logos or unaltered textures fall into the simple "images" category. The other field potentially usage is the "cat subject" (example). However, this categories are still being made, so you might leave it blank for now. Do not use these fields unless you are certain of how the image categorization system works.
