We kindly ask you to please properly license all future images that you upload to the wiki. It is the sole responsibility of the up-loader to license any image he/she uploads to the wiki. When uploading an image to the wiki, towards the bottom of the page there is an option to add a license. Click on the drop down menu; there on the menu in the lower section, you will see "fair use and with permission" options.
For images that are game screenshots, use Copyrighted Media.
For non-game screenshots (pictures taken from the web etc.), use Fair Use.
For images that are not licensed, or images you have made yourself, use Public Domain.
You add the license to the image at the same time you upload it to the wiki. For more help and details, see here. If you have any questions please contact me on my Talk page and I'll be glad to help.
