MediaWiki:Uploadtext
From Halopedia, the Halo wiki
Halopedia storage space is not infinite. Please check to make sure that the image you're about to upload doesn't already exist. Also, if you want to use a smaller image of an existing image, you DO NOT upload a smaller picture. Halopedia allows you to resize the image. For more info check out the Help section on Images.
When you upload a picture be sure to choose a license from the Licensing dropdown box. If you can't find a license listed that fits your picture then browse through the Image Categories. When you find where your image would fit, add the category in the Summary box.
