If you want to upload an image for use in an article, you must determine the copyright status of the image. If you know the image is in the public domain or bears a suitably free and compatible copyright license, upload it to the Wikimedia Commons instead of here, so that all projects have access to the image (sign up). If you are unsure of the copyright status, see the file upload wizard for more information, but please be aware that most images you find on the internet are copyrighted, are assumed so unless you have affirmative evidence to the contrary, and do not need to display any copyright symbol. Please also read Wikipedia's image use policy.
If you want to add a free image that has already been uploaded to Wikipedia or to the Wikimedia Commons, add [[File:File name.jpg|thumb|Caption text]] to the area of the article where you want the image to appear – replacing File name.jpg with the actual file name of the image, and Caption text with a short description of the image. See our picture tutorial for more information. I hope this helps.
