You have to have a url, so if you have an image on your local, you want to upload it to [color=39b54a]imgur[/color] and then take the BBC code and paste it in here.

If you have a link to an image IE you searched an image on google/bing and found a one you liked, then clicked on that image and it is now in the top right corner on its own, you can paste the url here - select the url then hit the button 7 across that looks like a picture :)
