I've gone back through the existing images and added licensing information and categorization. When adding new images you can add category information by putting it in the comment section when uploading however it's a bit awkward if adding lots of images so please don't feel obligated to do so if you don't find it convenient. Because there were over 25,000 images to update I created a tool to find and modify image pages in need of updating. Once a month or so I'll use it to catch any uploaded images that need updating.
Any image with license info included (the drop down box when uploading) will automatically be categorized as Category:Image so you don't need to add that one.
The other categories:
- Category:Artwork
- Category:Icon
- Category:Live Image
- Category:Map
- Category:Spawn Map
- Category:Splash Screen
- Category:Stats Panel
- Category:Symbol
- Category:Teaser Image
To add licensing information after an image is uploaded, add a "Licensing:" section and add the appropriate license template. For example:
== Licensing: == {{Promotional image}}
or
== Licensing: == {{Screenshot}}
