[[Image:{name}|{type}|{location}|{size}|{caption}]]

Before you upload an image, make sure that either:
* You own the rights to the image (usually meaning that you created the image yourself).
* You can prove that the copyright holder has licensed the image under an acceptable free license.
* You can prove that the image is in the public domain.or
* You believe, and state, a fair use rationale for the specific use of the image that you intend.
MAKE SURE that you do not violate copyright law!!
that is a crime and you can be sued by the owner of the picture.
