<div style="position: fixed; top: 0px; left: 50px; overflow:visible;">[[File:(NAME OF THE FILE and the tag, .png, .jpg, etc.)|thumb]]</div>

note you can change the "top" and "left" to bottom or right and you can adjust where you want to put the image by editing the "0px" next to top and left; the first 0px will adjust the y of the image and the second 0px will adjust the x of the image
