When you are adding a wikipedia page, how do you add a picture?

First, you need to become an "autoconfirmed" user (a user with a registered account at least four days old and with at least ten previous edits). This is but the beginning of the odyssey. By the time you work your way through the blizzard of "help" and policy pages on Wikipedia regarding uploading images and copyrights, it is fairly likely that your image will be deleted, unless you state that you actually own the copyright to the image. Even if you are the owner (being the original creator is one way), it still may be deleted. Some brief tips to save you some grief: if the image is actually copyrighted by another, it will have to qualify as "fair use" in order to be used on Wikipedia. The policy is not easy to comply with, and even if your image does, it still may deleted by a "free culture" zealot who is ideologically offended by "non-free" (English: non-donated or non-public domain) images. Also, you would have to find some image host acceptable to Wikipedia. The usual host for Wikipedia, Wikimedia Commons, specifically forbids the upload of fair use images. Even if you are the owner of the copyright, you will need to make clear that you are DONATING the image, not just to Wikipedia or the Wikimedia Foundation, but to the entire world. There are also a number to hoops to jump through here. If you find this overwhelming and not worth the trouble, you are far from the first to come to that conclusion. It is not for nothing that the New York Times refers to Wikipedia as a pictorial desert.

Unkown. How about you just don't.
