Nohing wrong with the url, you just added the wrong link in the img tags.
What you tried to do:
What you should have done:HTML Code:[IMG]http://imgur.com/MYauGDM[/IMG]
The first link will take you to where the image is uploaded, the second will display the picture when wrapped inside [IMG] tags. Hope this makes sense.HTML Code:[IMG]http://i.imgur.com/MYauGDM.jpg[/IMG]
