Forum:Images from external sites

I was hoping someone might be able to explain to me how to make an image show that is hosted on an external site. For example, I want to make an image appear in my signature that is 20px in size but is hosted on Wikipedia. I know how to show the link to that image, but not how to display the image itself. Any help would be appreciated. --| TrekFan Open a channel 21:39, March 20, 2011 (UTC)
 * Please do not put any images in signatures. The only place external images are allowed is on your user pages.
 * Do note that some user pages (ie Archduk3's) have examples of off-site images used. -- sulfur 22:05, March 20, 2011 (UTC)
 * To clarify, MA:IMAGE states "Finally, images are not to be used in signatures, and any image link used in such a way will be removed by an administrator."--31dot 22:08, March 20, 2011 (UTC)

Oh, I guess that idea's been well and truly crushed! Never mind, it's not big issue anyway. --| TrekFan Open a channel 22:51, March 20, 2011 (UTC)
